That is not 2-digit number.
A few historical trivia may help.

Originally we said "you can use -M2 to choose 2/10" (like "gzip" taking compression levels between "-0" to "-9"). Then Linus came up with a clever idea to let people specify arbitrary precision by letting you say "-M25" to mean 25/100 and "-M254" to mean 254/1000.

Read the numbers without per-cent as if it has decimal point before it (i.e. -M005 is talking about 0.005 which is 0.5%). Full hundred per-cent has to be spelled with per-cent sign for obvious reasons with this scheme but that cannot be avoided. It is a special case.
