Hi Matthew,
Are you working on improving the tire economy of your car(s)? or are you not pushing on your hard compound during races?
My guess these are the most probable reasons for the behavior of your hard tire.
(Of course the track characteristics play a role there, specially the tire wear rate of the track).
Once I use hard tires I always push harder on them and at one point I had the highest rating on tire economy in my league. This is why it confuses me that even teams who r smaller can beat me on the same tire
