Well , it looks like I think you did a much better job than Larry... I have no idea where he is coming from on the leak deal...
There are only two ways which a properly pulled vacuum will go away... one is a hole in something... or a leak past a seal...
OR that their was moisture in the oil which boiled off ...
If you pulled a good vacuum, read your guages reasonably close at the first and last of that operation and they had not moved I think you did a good job.
Remember on taking the picture of your thermostat... the low temperature is taken with the interior fan on LOW... that will give you closest to the evap terperature for your thermometer ....
Unless there is air taken into the system you do not have to assume that moisture entered it ...
However, it never hurts to vacuum more.. so doing it again immediately before charging is great... and remember to put newly opened oil into your vacuum machine...
