I posted this originally as a question but received no official response.
Next day I posted it in the Crafting section.
http://forums.elderscrollsonline.com/en/discussion/160577. Someone suggested I post it here but I figured I should give it another day.
I filed a bug report but I don't expect a response to those.
I have a ticket in. Received no answer. Filed another ticket two days ago with links to the following screen shots.
Same value for all four despite each being a different level bracket. Still no response from support.
The Monumental Glyph of Stamina does show a higher value. No matter the aspect rune the brackets report identical values. Tried it at different enchanting stations. Same result.
Something like this warrants an official response. Clearly. Thank you
