Hi, I thought this would be an important issue, but have only seen chats in discord. I now suspect we may end up with a mixed calculation at payout. If one looks at the data on steemd, the "weight" column means curation-weight and is calculated at the time of voting and includes factoring in any curation loss due to voting before 30 minutes. I suspect recalculating all of those to take account of the new 15-minute reverse auction will not happen, hence everyone will be paid their curation rewards under HF19 terms. However, the curation amounts that end up going to the author, the author_curate_reward, may well be paid to the reward pool as per HF20 - unless there is specific code to not do so for posts published pre-HF20.
