agree, but that's the laws of the game... It's not VAR you should be angry at.
out of interest, how offside should be allowed ?
I think this is the main problem with the stat you quoted about there being more correct decisions with VAR, it seems more likely that the decisions are 'correct' because the laws of the game have been rewritten to suit VAR.
The Raheem Sterling Champions League example you were talking about shows the difference between the two sets of laws being used. I don't think at the time of that game the laws had been changed so during that game the benefit of the doubt should have been given to the attacker (it wasn't) and the fact that the player was coming from an offside position and moving into an onside position, therefore gaining no advantage, should have been taken into account when determining offside (it wasn't). So using this example that you've been discussing, VAR was actually used to give a decision that was actively against the laws of the game and therefore, wrong. It may have been correct when compared to the VAR guidelines, who knows though as they seem to change every week.
Since then the laws have been changed to suit VAR, no benefit of the doubt to attackers as it's now a black and white decision like goal line technology, except it isn't as the technology doesn't work well enough for it to be used that way. If we're assuming that the person freezes the frame at the correct point then maybe we are getting these millimetre offside decisions correct now so that goes towards your percentage stat increase of correct decisions. We had to actively change the laws of the game to get to that point though by removing benefit of the doubt to the attacker.
Handball is the same, if you change the laws to suit VAR better then you get to the point were at now where any kind of contact is a handball. This is great for the correct decision stats but a disaster for the game, which is why they appear to have changed the laws again.
You also keep saying that VAR has stopped diving but it absolutely hasn't, all that's changed is the DEFINITION of diving has changed. Diving used to be when a player decided to go down to make it look like they had been fouled and that seems perfectly fine to me. Now it seems literally impossible to dive, if an attacker has their arm ever so slightly brushed against by a defender and then, for some inexplicable reason, their knees buckle and they throw their arms in the air while throwing themselves to the ground then that isn't diving now as VAR shows us that there's 'contact' and he's now 'entitled to go down'. We had three penalties given against us against Leicester this season and all three of them were dives as the player wasn't forced to fall over, they DECIDED to fall over. It's OK though, VAR looked at the referees decision and they could find a slight bit of minimal contact therefore it's the correct decision, hurrah! Another one to bump up the 'correct' VAR stats.
VAR is an absolutely pointless addition to the game, the laws have been changed to suit it to the detriment to a sport that's worked for well over a century.
The biggest reason for all this is that there has to be controversy and talking points when you have 24 hour rolling sports coverage. The vast majority of the 'wrong' decisions made in games were actually perfectly acceptable to the match going fan, close call offsides went for you and against you, some fouls you got and some you didn't. It was all part of the game but now with Sky winding up the armchair internet not-rights, every marginally small incorrect decision is a huge travesty to the sport that has to be discussed to death by pundits and experts (particularly when it goes against a team that has a huge worldwide following, why else do you think some referees are afraid of giving decisions against Liverpool, United, etc? In my opinion it probably isn't brown envelopes, it's more likely they don't want Carragher, Neville, Aldridge, et al dragging them over the coals on the TV and in the papers for a perceived injustice against their team). A good example of this is from a few years ago when City knocked Everton out of one of cups. The winning goal came from a cross that almost went out of play for a goal kick. Looking at it from a lot of camera angles it looked very much like it should have been a goal kick but during the game a shot was shown looking directly down the line, it was clear it didn't go out and that it was a perfectly good goal. Obviously, that clear shot of the ball in play was never seen again but all the other angles were all over Sky and the papers, it gave them a good weeks worth of clicks, have your says and phone ins which is all the sporting press are after. "Ball looked like it went out of play but actually didn't" doesn't get quite the same attention or air time.
VAR in and of itself isn't the worst thing in the world for the sport, the way it's used is. Referees need to make their decisions the way they used to rather than worrying about VAR and the VAR operator shouldn't be afraid to tell the referee that he's missed something. This is where the frustration for most fans comes in, it's ridiculous when you see a stupid decision in slow motion from multiple angles and you know the VAR guy sees the exact same stupid decision but does nothing about it because 'it isn't a clear and obvious error'. They also need to be much more consistent to all teams with it, if referees are constantly giving the benefit to the same teams then VAR should be stopping that by pulling them up on it during games, if it isn't fair and consistent then it will never be accepted. It's one thing if a referee is a bent bastard during a game but it's so much worse knowing that there's another referee watching all these decisions and doing nothing to change them EVEN THOUGH HE CAN AND THAT'S HIS ENTIRE JOB! They also need to stop equating 'contact' with 'foul', at the moment VAR is just a licence to cheat for players that way inclined (Mane, Salah, Vardy, that cheat at Utd who's name I can't remember, etc).
Sure VAR can spot if an attacker is maybe a millimetre offside but who cares when it doesn't spot blatant handball (Alexander-Arnold), pushes in the box (Gomez? V Sterling), attacker fouling the defender in the build up to a goal (Lyon's second goal in the Champions League last season), a goal being scored from the arm (Spurs in the Champions League), can't spot a blatant dive (Liverpool, Utd, Leicester pick a game
) or is used to wrongly chalk off a winning goal due to an incorrect offside decision in a Champions League knockout game (Spurs again)?
Most City fans see it this way, sure its given us some fairly inconsequential decisions (retaken penalties due to encroachment, stuff like that) in games that either didn't matter or we were already well ahead in but in the big crunch games when we needed the decisions to be correct and the application of the laws of the game to be fair and equal to both teams we did not get that.
In answer to your question though, for offsides the VAR/referee should get 5 seconds to look at the still shot of the players, without the computer lines being drawn on it, and if he can't see someone is definitely offside then use the actual laws of the game and give the benefit of the doubt to the attacker.
