I do show that both of you are at 4 shares. Your shares determine your portion of the total weekly voting weight. Your upvote weight is then divided by your posting frequency. Since you are posting more frequently than the average member, it looks like your upvotes aren't any higher, but remember you are getting more of them.

At your posting frequency, if you didn't have the extra shares you would have been slotted into pool 2. Even if your upvotes are only 1% upvotes, they are still more than than the 3 or 4% upvotes you would be receiving in pool 2.
