Setting Glide speed in Aircraft Profile

A small thing, but here it is.

I am trying to set my glide speed in my aircraft profile.

For some reason, it will not accept 65 mph as my speed. I set 65 and it either sets 64 or 66 mph. I can set 75 or 55. Just not 65.

I brought this up last year and Brian explained that no matter the input unit-of-speed you use, the software stores it in knots, then displays that number (converted back). So in effect, it can't display certain mph numbers. (I.e. it's a conversion/storage-precision issue.)

John,

Hook is correct. iFly always stores this in terms of knots.... and 56 knots converts to 64 mph, but 57 knots rounds up to 66 mph!!! and so 65 mph is not possible.
