Please Address: STA > HP Confusion

[ccs88]

I had authored a section in the wiki 1-2 years ago concerning STA to HP conversions (see attached image for my original work).
I recently went to reference it, and noticed that somebody had removed the soft caps from my chart (see the new chart and the post that initiated this change).

I had based my evidence on personal testing, forum research (see this post from Daldaen and this post from Cecily for example), and verifying the conversions via the Magelo profiles on the wiki.

If I'm wrong here, then please provide some real evidence other than some heresay from a few randos.
Some insight from the devs would be great, although I can reference a 2014 post from Daldaen already.

Thanks.
