I agree with your point but not your logic... You are using 36 because it is 365 per 10 days, but if you start on the 1st of the year, you get 37 cycles of incoming tech (last cycle is only the last 5 days of the year but lyricaz records at the send, not the expiration of aid slot).
- Pink received the +1 slot 3 times this year.
- Using similar logic to the 37 cycles, in a +1 slot event one could get +4 aid offers per event => 400t.*
Still 37 cycles * 600 tech/cycle + 400t/event * 3events
This still would leave the ABSOLUTE maximum at 23,400 tech.
The only explanation of the 25.4k tech number would be if it included other sources of tech. This could be the 720 tech (60tech/$30 donation * 12 donations a year), 100t / referral, raids etc.
* = your refute would be that once the event starts you get that 7th slot, so it'd be impossible for you to get 4 7 slot offers in because your 7th slot started on the 1st day would expire on the 31st, which seems to be sound logic however the way the 7th slot is coded is that it allows for 7 slots total at any given time, so if you have full 6 slots and then get that event, you could hypothetically use your next expiring slot as a 7th slot during the last week of the month.
