1% of 126BPM is 1,26.
The difference is 0,05% so the difference on the BPM is 0.063 BPM what ridiculous to care about....
But trust me - there is no need to care so much about making the numbers the same - for many years, the resolution of the pitch slider on the cd's was 0,1% (that might be the reason why your NDX was stepping 1.9 to 2) and everyone was ok with that and the mixes were smooth.
Relax, trust your ears and don't care much about the numbers - thats the best way how to make a tight mix.
