thanks for the quick reply, I see what the calc is doing now. it has a small range for what it estimates the diffulty would currently be if it were to adjust in real time. I'm a lil lost on your math though, how did you come to the 268?
a - (b % c)
a = amount of blocks in a difficulty period
b = current block
c = amount of blocks in a difficulty period
% = modulus (remainder of a division)
You start by calculating b % c, which is 1 748. This is the amount of blocks currently found in the current difficulty period.
Then you calculate a - 1 748, which equals 268.
