Sry for my english.
I made same definitions for Small Blind (number of hands on effective stack).
Total hands from SB: 13185 hans
Total hands from SB: 00-08 BB = 3447
Total hands from SB: 08-17 BB = 2728
Total hands from SB: 17-25 BB = 2481
Total hands from SB: 25-35 BB = 2299
Total hands from SB: 35-50 BB =1826
Total hands from SB: 50+ BB ( more than 50 b=BB) = 404
Total Opportunities = 1385 Hands All is ok 1826 + 2299 + 2481 + 2728 + 3447 = 13185
After I made a definition named Total Open = ( Open, mini Open, Shove) for same number of blinds: 00-08, 08 17, 17-25, etc
The number off opportunitied is not the same:
Total hands where action is Total Open from SB: 13185 hans
Total hands from SB: 00-08 BB = 413
Total hands from SB: 08-17 BB = 1841
Total hands from SB: 17-25 BB = 2318
Total hands from SB: 25-35 BB = 2501
Total hands from SB: 35-50 BB = 2753
Total hands from SB: 50+ BB ( more than 50 b=BB) = 3447
Total Opportunities = 13185. Total Open Hand is not ok 413 + 1841 + 2318 +2501 + 2753 = 13273 NOT 13185
The definitions are for HU SNG.
