I think,the numbers are accurate,bar Troops.....Troops has to be a rough guess,IMO.Clearly not, but the numbers are likley provided by Ukraine so there is a bias. Less so than the Russians clearly.
Artillery pieces,AFVs,Drones,Aircraft,Tanks etc.....They know what has been hit.
This is my opinion only.
Some of the vids i have been sent,regards bases etc...you would not know if there was 50 in it or 500,there is nothing left of some of them.
Slava Ukraini.
