Sometimes they may bring interesting and valid points worth considering; things which we, "professionals", may not have thought about or realized. So, thank you kindly for your input. ... >> Bearings: >> >> I'd use 00-09 for the first quadrant (the fundamental unit to use here would >> be the grade/gon), > >and I'd use 000-999 for the first quadrant... >1000 mq -1999 mq, for the second... >2000 mq - 2999 mq, for the third, and... >3000 mq - 3999 mq for the fourth. > Understood, but the difficulty with your suggestion though, Pat, is that it has too many digits, unfortunately. Our current system already works with "decadegrees" for that reason. Besides we would not need that much...

However, a mq being 10 km would be insufficient now (as opposed to the previous issue) for navigational purposes. Please remember my previous point of the inexistence of a power of 4 prefix (or minus 4 actually, in this case).

Here, however (a minor point perhaps), 3 digits would be more adequate (please remember that the "poor of us" would feel more at ease around numbers not exceeding 3, *tops*!).
