Thank you for the additional detail. Sadly, I thought that the status earning and upgrades-without-reset would start in January 2026, with SP earned in 2026 counting towards 2027 [as well].
I can select 300 SP if i pick just individual sectors in a non-chronological order. If I was to claim them all in together, and CX processed them in their own order, my status point reset would lose me some points (e.g. if I did 75+75+70+45+60, I get 330, and would lose the 30 points). The final question was to see if CX processes in order of submission, or something else more random. If more random, I would need to ensure that the 300 is triggered first, so that they don't credit in an order that would lose points. the 75s are CX and would go first anyhow.

In short, seems cherry-picking would work and I can avoid losing if I submit and wait for it to clear. It might just take a little longer.

Good luck to CX admin staff with all these retro claims come January.
