Text height is wrong
When you select a specific text height, it is not correct. Say for instance you select 1 inch for text height but in reality the cap height is .68 inches. We work at a sign shop and a lot of jobs require a specific text height. This is misleading when I pick 1 inch for text height and it is no where near 1 inch in height. Can you please make it where the text height corelates to the actual cap height of the text, otherwise this feature is useless.

Latest Illustrator releases have Font Height Options you can access form Character panel’s menu — they allow you to set font height as a capital / x-height specifically.
The functionality has some minor issues (regarding rounded stems for some fonts, keeping the chosen option between launches), but otherwise it is very good. Please try it!

I am using the implemented cap-height feature. It is not scaling to the actual cap heigh of the font's metrics, rather, the largest of the glyphs. it does not allow for a consistent experience.

Jay, be default the font size measure by Em Box, the invisible container that surrounds all ascenders and descenders of a glyph. There was no way to set a font size by defining its capital letter size or x-height. It used to be like this for ages.
But recently the team picked up this feature:
https://illustrator.uservoice.com/forums/333657-illustrator-feature-requests/suggestions/32403763-allow-to-set-font-size-by-setting-x-height-and-cap
and you can try it in the Beta or wait till next release )hopefully).
Have fun!
