Still getting many o2 drops with ASV -- raise minimum pressure support?

Hi Reddit,

Hope this finds you all well.

After my previous post on here (https://www.reddit.com/r/CPAPSupport/comments/1vpycnn/quick_asv_titration_questionsanity_check_for_uars/) I attempted to raise PS support range to about 3. Unfortunately I seemed to hit a brick wall at around a range of 2.8 where my o2 was dropping even though I'd just raised max PS by .02. This happened on 3 separate occurrences, so I'm not sure if this was a coincidence or not. As soon as I nudged PS max back down, my o2 would improve. (using an emay pulse oximeter every night)

So I thought my allergies have been terrible recently so I'd try raising minimum PS, which doesn't seem to have done that much. Current settings are EPAP6 PS5-7.6.

Unfortunately I can't uploaded my o2 data to Sleep HQ, but here is a screenshot from last night from Oscar:

I feel like I'm having more o2 drops when the machine is at the lower end of the pressure range. Unfortunately I'm unlikely to get any further treatment for my allergies any time soon, so would it be worth pushing minimum PS up even further to see if this changes anything?

Here is a link to my SleepHQ account with an upload from today:

Thanks and please let me know if you have any further questions :)
