I've gone through your example of a Belotto's drawing process on page 19 and 20 in the whitepaper and there are some issues

First, the hash is in hexadecimal, so only A through F would be present.  So including G and subsequent letters is useless.

Second.  There is an inherent error in the logic where the drawing algorithm can select "00" but it is not allowed in the number where 1-60 would be valid numbers.
