I allways configure PCB to increase the hole not in 5 mils step, but in 4 mils 
step, and my footprints have drill size multiples of 4, so I have drills that 
are very close to 0,1mm multiple. Thats because my pcbs fab have drill from 
0,3mm to 3mm in 0,1mm steps.

I agree, but I dont have sufficient IQ to do it... :D
