Bitgrin have 2 algo :
It is a rule of thumb,
if your GPU has at least 5.5 gb but less than 10.5 gb
you have at least or close to 11 GB
This is not necessary true since miner develop C31 for GPU with lower than 11 GB, but it will give low performance.
Initially 6 months after genesis, C29 (90%) vs C31 (10%) was due to decrease by 3.75% each month until they hit 100% block reward on C31 (that would have taken 2 years)
