You are measuring 120mm of filament and telling the printer to use 100mm. Once perfectly calibrated with will leave 20mm filament exposed.
It may be clear; but is not expressly stated that the aim is to result in a final measurement of 20mm.
Potential text example.
Step 10:
"To objective is to see 20mm exposed filament between your two measuring points. Once reached, save your current, calculated rotation_distance permanently:"
The guide is very helpful and I understand is a balance between detail and clarity, so this is an optional suggestion. Thank you
Step 10 on this guide does not clearly state the target outcome / final desired measurement.
Stating what the end goal is would be helpful / more clear.
