Hey Run It Once community,

My question might have been asked a several times, so i do apologize if it is the case.
I was doing some calculations on Bubble Push or Fold situations with holdem ressources and i was wondering if you have any tips to get decent results when we are multi tables? Because obviously chip ev calculations are not right. I thought that maybe i could get a better idea of the right results by doing this following process, tell me what do you think about it.
Let's assume for example that we are 28 left in a tournament and 27 are getting in the money and that we are nine handed at our table.
If i put in holdem ressources only 8 prizes as if i was in ft and we were only 9 left in the tournament and i am doing ICM calculations. do you think that i am getting close results to the truth by processing that way or that i am being totally wrong and that you would advice an other method?
Thanks very much for your help,

Paulo
