I think the dev needs to clarify the rule of posts per week.
Rather, if the distribution time occurs, the posts that were not deleted this week will be counted. (Older posts deleted are not relevant)
It seems dev is currently evaluating activity according to the total number of posts at the time of the spreadsheet.
If this week you have a smaller total number of posts than the previous week (the time when the participant list was created), you will be ignored that week. That's not fair.
