Sometime I can get close using my method at 2Nl . my inaccuracies are tiny at these stakes,but bigger stakes would men larger errors.

I wondered if anyone had a better method than im using.

Im trying the methods suggested ^^^^^ divide by 3 , multiply by 2.

The pot became $5.55 , I got brain freeze. couldn't divide by 3 at the table.and rounding it to $5.40 gave me $3.60 , still too small
