Seemingly, this is the same 1M per year amount from referendum 1212 only divided into two semesters. The refill timeframe seems to be the only factor that's changed. It's a positive overall as reducing the DOT requested by bounties to shorter timeframes helps reduce the impact when price goes up.

However, the deplete and request approach for bounties is something we really dislike as it has proven to be a detrimental approach for the treasury on previous bounties. So we really would like to see a set timeframe also requested before by us

FAQ 1374

1374 Budget

1212 Budget

This requirement is now is also a part of the bounty compliance set by referendum 1254. Paragraph 2 section 2
https://polkadot.subsquare.io/referenda/1254
so early refills are discouraged at this point, attempting to comply with the requested amounts at the previously announced dates is encouraged. In short, requesting the refill around the 6 month mark or after should be alright but requesting it after 3 months because the bounty got "extremely successful" is something that should be really discouraged.
