I have been reading up on the roasting approaches for the Behmor Plus and am trying a roasting method that a few people have recommended. The weight loss I end up with seems too much compared to the corresponding colour of the end roast. Is the weight loss ratio guide that came on a roasting spreadsheet I found online incorrect? or is the end weight not relevant when trying to judge roast level?
The guide I am using for weight loss compared to roast level is as follows:
The two roasts I did today are below:
Roast 1
Bean: Peru Ceja de Selva AA
Start weight: 390g
End weight: 321.2g (loss of 17.64%)
Profile: 400g P2 B Start, P4 at 12 mins, FC 15:30 P3 D, 18 min P2, 19:30 End
Roast 2
Bean: Costa Rica Miel SHB
Start weight: 390g
End weight: 323.4g (loss of 17.08%)
Profile: 400g P2 B Start, P4 at 12 mins, FC 15:00 P3 D, 16 min P2, 19:00 End

The guide I am using for weight loss compared to roast level is as follows:
| Start | 390 | Percent |
| Cinnamon | 347 | 10.93% |
| American | 344 | 11.82% |
| City | 340 | 12.70% |
| City Plus | 337 | 13.58% |
| Full City | 334 | 14.46% |
| Full City + | 330 | 15.34% |
| French | 327 | 16.23% |

I have printed out the CS colour scale so now I can accurately measure the roast colour in CoffeeSnobs language. The Peru and Costa Rica look like a C9 to me while the Indian looks like a C7/8
