### Etymology

Named after Paul Magriel.

### Noun

M-ratio (uncountable)

1. (poker) A measure of the health of one's stack: the stack divided by the sum of the small blind, the big blind and the antes of each player. The result (M) is the time (the number of orbits) it would take for one's chips to deplete if the player only passively places their forced bets and otherwise folds.
${\displaystyle M={\frac {\mbox{stack}}{{\mbox{small blind}}+{\mbox{big blind}}+{\mbox{total antes}}}}}$
A player in an eight-player game with blinds of $50/$100, an ante of $10, and a stack of$2,300 has an M-ratio of 10:
${\displaystyle M={\frac {2300}{50+100+(10\times 8)}}={\frac {2300}{230}}=10}$
