It would be good if they had the "Effective M " stat avaible in HEM2. Effective M is what your M actuly looks like on short handed tables.
Example... if your M is 10 and there is 4 players left you have take your Basic M which is 10 x by the number of players left/10. so it works out to be 10x0.4=4.
