Perhaps another way to look at it is to observe that 46.5 x 11 = 511.5.  That is suspiciously close to "exactly" 512.000 - in other words is a 9-bit binary shift which is arguably what you'd expect a presumably fixed-point microcontroller processor to do to represent two levels of resolution or scaling of the same underlying value.

 

Stan, you may be onto something here. The 46.5 number I use was derived by working backwards. With a little more 'tuning', it really could be 46.545454 and then 46.545454 * 11 = 512.
