I’m reviewing my database to improve my preflop game in spin and go. Here are my results for defending [K2o,K3o…K7o] in BB vs BU ( 3 handed ) and SB fold. You can see results here:
(Below I took 60 as standard deviation cause I think there is a mistake with the average made by PT4)
I calculated a confidence interval for this sample and got this. Copy and paste from google spreadsheet formula:
Confidence interval wanted: 90%
standard deviation (bb/100): 60
hands/100: 1,6 (sample is 160 hands)
results (bb/100): -125,51
Confidence interval: 98,69 (bb/100)
Confidence interval with results: [ -26,82 ; -224,20 ]
- Are my maths correct here?
If so, given this confidence interval I can’t conclude folding is better than calling for those hands.
I’d like to make sure both my maths and methodology are correct here so I can check various preflop situation.
What do you think?
Thanks a lot!
