Just to supplement Crazy Teitoku, as I was the one who put the pages up and used the letters...

The lettering was a completely arbitrary suffix I put on the forms because at that time I had no information as to which was stronger or which was weaker. Note that the devs have set precedent of higher api id = stronger as well as lower api id = stronger, so it's really not a reliable way to tell which is the stronger form (and of course, in the future, different forms may not be so clear cut as to be stronger or weaker). Probably from here on out, they will be lettered in increasing order of implementation date, then api id. Of course, if someone other than me ends up creating those pages, anything could happen.
