...the failure, and next time, generate a number from 1 to 5, but add on say, floor(numFailures / 2). So this time, again, they have a 1 in 5 chance. If they fail, next time the winning interval is 4 and 5; a 2 in 5 chance of success. With these choices, after 8 failures, they are certain to succeed.

Example 1: Suppose
X = 100
M = 1
R = 2
P = 1
Then C = floor((X-M)/R) = 49, and cnt = ceiling((P - (X - M - C*R))/R) = 0.
Example 2: Suppose that
X = 100
M = 1
R = 5
P = 12
Then C = 19, and cnt = 2.
