So in not exactly 2us but (1/7093790)*2*7=1,97356us
In a rotation you have (,200/dur)=101340 cells

You need to allow for motor variations, eg Teac 235HF allows up to +/- 2%. Even assuming standard length 101,340 bitcells it would therefore be sane to allow a min track length of just over 99,000 bitcells.
Also consider that your ADF may not be written on an Amiga but by eg Catweasel, Kryoflux, Supercard Pro.
EDIT: The insight on Paula bitcell generation is useful though thanks. I will confirm by logic analyser and probably increase my ADF track length in that case. But I certainly still argue that your loader is not sufficiently conservative.
