If 2nd number is higher than 1st its most likely VPIP/Openraise, but usually it's VPIP/PFR. Some add 3bet, Steal, AF etc.
I use:
- HEM for tracking results, HUD, and reviewing hands
- StarsHotkeys ahk
- TimeoutHelper ahk
- SessionCounter ahk (current/total tables, session duration, total/avg BI)
- a selfmade ahk to move tables to different stacks and one-click-reg
- SngWiz for training and analysis
Holdem Manager and Table Ninja for use during play is enough for most people playing sngs/mttsngs seriously. Get those two and learn to take advantage of them in your game and THEN you can think about if you need any other software, my guess is that most players say no.
Of course you cant live without SNGWizard when you are learning the game.
