The more i think about the new CR1 earning structure, the more I think its UA's way to spread more of the CR1s down to lower elite levels.
think about it -
1) although 1K's might get less, a lot of Platinum and 1P's will now get 2 or 4 or more CR1s.
2) also, one can now earn CR1s during the time they build up to 1K rather than only BIS miles AFTER attaining 1K.
3) also, if you fly heavily in one quarter, but none/little in another quarter, the cumulative EQM system would benefit you over the BIS-per-quarter system.
Overall, although its not likely an improvement for most 1K's, it would be for many sub-1K's, and those just building up status to 1K. And there are way more 1P's/Platinums than 1K's in total.
So it may be a redistribution of CR1 earning potential somewhat, but from UA's perspective, the new system might be a wash in total CR1s handed out - while encouraging lower elites to fly more UA/Star.
