A great many, hundreds and probably thousands now.
There was a survey done many years ago. I forget when it was but could have been in the 1980s about this subject. It found that 70 people had been murdered by released murderers since the ending of the death penalty in the 1960s. The figure was relatively low for 2 main reasons. Only around 70 murders used to happen every year in the 1960s and if the murderers got life it meant at least 15-20 years or more so a relatively small number had been released.
We average around 1,000 per year now and the sentences are lighter and often result in release in less than 12 years.
Undoubtedly the figure of 70 from the 1980s will have multiplied by 20 by now easily.
I'm not sure where you've got these figures from fella but they don't stand up to much scrutiny.
Figures aren't readily available over a long period but since 2007 there have been seven people convicted of murder who were on a life licence. Possibly but by no means certainly were all seven previously convicted for murder. Source: The Ministry of Justice.
Assuming by "we" you mean England and Wales, we are currently averaging no where near 1000 per year.

Also, without having any figures at hand to back it up, it is generally accepted as fact that minimum terms ( tarriffs ) for mandatory life sentences have gradually been rising in recent years, not reducing.
