Absolute Ring Event

The Xenon Update Notes state "Absolute Ring + all previous Absolute rewards: 31 - 33 stamps", that it specifically states 33 as a cap makes me believe that the intended max number of stamps we're to get is 33, and the extra day is really there as a sort of fluff. This also means even though you can miss 5 days and get an absolute ring, they can't be 5 consecutive days, or even 3 consecutive days in any given phase.

I mainly responded to clarify for people who got Lv 11's already and couldn't get a stamp for the extra day, but also noticed that some people are saying if you missed the first five days, you can still get the absolute ring. But no, I do not believe this to be a glitch, just misleading.

Edit:
For those that missed 5 days but really really want that absolute ring, I thought of a gamble you can try. Half way through phase 2 and 3, chuck your ring. A new one wouldn't reach level 11, and that might just let you get a 13th stamp on the last two phases. Not sure if it'll work, but if I were in that position, I'd at least try it on one of my mule chars. It would mean you won't get any lv 11 rings.
