Which is the best calculation for growth?

... calculate growth based on N0 and Nt? What I came up with is that...and I am wondering what do you think is the most accurate of these : 1. "Biomass accrual" Nt-N0 2. Nt/N0 (just a ratio!?) 3. The number of doublings/cell divisions? = log(2) Nt/N0 In was using the later one, but not ...
