Unfortunately there are a couple pitfalls with this approach… As mentioned, temperature is one, but more commonly altitude. HFR changes with altitude. Issues I see:
- It is possible for HFR to stay within band and be out of CFZ. This is especially true if the baseline HFR is captured with the target at lower altitude. The same HFR, but higher in the sky, may not be in focus at all.
- This is a complicated user setting… we try to avoid that when possible. It would be difficult to calculate the “bounds of HFR” with respect to CFZ and I think we would spend a lot of time supporting this.
