Is there any font classification service (web page, app, book) that classifies fonts by x-height, ascender and descender lengths, stroke contrast, apertures and counters, besides the basic serif and sans-serif classifications? Also if if the font is made for heading, body, etc.

Although I once had college-level schooling in fontography, my skills are time-blunted. Please help me to locate the name of the ascender-/descender-modified font in the logotype. I am thankful for any help you can give.

Please help me to understand how UPM is related to ascenders and descenders. For example, look at Times New Roman (TTF) metrics, UPM = 2048 (see image below).

I used to believe that UPM = Ascender - Descender, but now I find that I was wrong. But what metrics expression must be equal to UPM? What plus what (or minus what) must give exactly 2048 in this example? I don’t see appropriate values at all. Help me to clarify, please.

Seems like there are some pretty merciless critics here, so give it to me straight. This is my own job of the extra R swoosh. Any suggestions?
