F1 23 Telemetry - Tyre Damage

Hi, 

Is the data for tyre damage on f1 23 bugged, or am I missing something?

I have created a telemetry tool in C# and during testing I found that the data from m_tyreDamage only appears to be correct for a specific tyre when the damage reaches 100%, otherwise it is 0.
Am I wrong in assuming that the damage from scraping a tyre on a wall should be included in this variable? 
All the other data from the damage packet is accurate and aligns with the in game visuals.

To verify that it isn't due to my implementation, I have analysed the raw bytes and found no difference, additionally I have tested this with someone else's implementation and get the same result.

Any help will be appreciated. 

Thanks.
