it can be, it's not as helpful in the 180 mans compared to the 9 mans for the pure reason that we only really use sng wizard for final tables. it has little to no use at all until then.
also, there is a hell of a lot to learn first before you can even utilize sng wizard properly. at the end of the day, it's just a calculator, and just like any calculator, it's only as good as the person using it.
so what will you need if you are willing to learn?
1. learn ICM inside and out.
2. learn how to properly use sng wizard, the tweaks you need to do to peoples ranges
3. learn the downfalls of ICM and how to compensate
4. learn about edge, and how to compensate
5. learn how to review your own hands objectively
if it sounds like a lot to learn, it is. but unless your willing to do all that, then the $100 you spend on software is better off in your bankroll. it can actually be harmful to your game if you use the software incorrectly.
