I'm having trouble understanding the second part of your yeast growth model.
I understand the first part:
If (initial cells < 1.4 Billion/gram extract)
yeast growth is 1.4 Billion / gram extract
Assuming 1L of 1.040 wort using 114g DME:
1.4*114=159.6
I don't understand the second part:
If (initial cells between 1.4 and 3.5 Billion / gram extract)
yeast growth is 2.33 - 0.67 * Billion initial cells per gram extract
Assuming the same inputs as above:
2.33-.67=1.66
1.66*114=189.24
The BF calculator says that there would be 155B cells of new growth; not 189B.
I suspect that I'm screwing up the last part. Instead of multiplying 1.66 by 114, I would multiply 1.66 by 93.37 to get 155B cells. What does 93.37 represent?
