Highest possible WR?

[Peacedout]

I tried using the search function and found a few articles referring to 58% and 63% win rates. Bascially what i am asking is what is the highest possible win rates for levels of 5-20dollar HU sit n gos. Also does Omaha vs holdem have a different maximum WR. Sorry if this is stickied some where or frequently asked. I looked for about 25mins and couldn't find anything.

Also What is a good program for recording hands for Sit n gos. I am not to fond of poker track for this use.
