Thanks for the feedback.
1) All Stabilisation patches are generated after every other patch - Drift, or Measured.
That is correct, as any patch will cause possible 'heat' issues, so will always need a Stabilisation to counter that.
The Stabilisation patch will therefore have the same 'impact' of Drift, as every other patch.
2) We can't replicate this - can you please provide further info?
3) Again, we will need to have further info.
However, if you mean the Profile in the following post, that lacks full range stimulus values.
What was the patch set was used?
It appears to have Limit Range active?
That is a very special use case for burnt-in PQ HDR, and you need to understand its application, as per the User Guides.
