The 28 upvote target is based on regular upvotes on daily updates. I looked into relative targets (based on % of actual updates upvoted) instead of absolute targets. The factor that you're not considering is the maintenance load. For the same effort required to continuously adjust relative targets instead of absolute targets, I can publish the daily updates and it becomes a moot point- since upvoting only the daily updates is sufficient if we are actually publishing them every day.

The target is 28 full upvotes, and there is currently no benefit to upvoting in excess of that. While your concerns arise from the number of upvotes you have given on comments which did not actually pay out, you were not actually rewarded for most of those upvotes under the current system. You have 99 full upvotes in the last month, and only 28 of those contributed to your bonus.

The whole reward system for upvotes will be revamped when we finish our fully automated system. At that point, we will be looking at % of rshares actually paid out, so any dusted upvotes will not be captured.
