RE: Pattern weight rule - why?
.
Actually, it was back in the days before printing presses, when scribes would sit in dark halls of the church and copy the FAI Sporting Code and AMA Competition Guides word for word with quill ink pens by dim candle light.
.
Apparently a typo (write-o, copy-o??) was made when one of the new scribes was copying the word "minimus" , and wrote "maximus" instead.
.
Yes, in those days the rules for pattern were written in Latin . .

So get over it Ye Plebes of the Proletariat and Eat your Gruel . . . .
