My room is cold , often 21 degrees Celsius or less
So I exhale warm air, the outside of my mask is cold, so water vapour builds up inside the mask and then loosens the seal of my mask as well as giving me a wet face.
"The air we breathe out is warm and moist, as it contains water vapor from the lungs and respiratory system. When this warm, moist air comes into contact with the cold outside air, the water vapor quickly condenses into tiny liquid water droplets. This condensation occurs because the cold outside air cannot hold as much moisture as the warm exhaled air.
The temperature difference between the warm, moist air you exhale and the cold outside air causes the water vapor to condense. This is similar to how water vapor in the atmosphere condenses into clouds or fog when warm, humid air encounters cooler temperatures."
In addition to make matters worse, I get rainout in the tube as well which can pour into my mask
So if we stop / reduce the rainout in my tube then all I need to do is find a tube cosy equivalent for my mask, not sure what that looks like and even if it exists.

Last night with the tube temp set to 27c and no water in tub I still had condensation in the tub but luckily it did not come through to the mask. That's despite using a hose cover and hose hanger.
For the mask I just used tissue to line the inside and although I had condensation in the mask that turned to water vapour the tissue absorbed it.
Now I am baffled how to line the inside of my mask on a daily basis to reduce the condensation by mopping it up inside the mask, any ideas?
My room is cold and it doesn't help. The answer would be to heat the room but in the middle of summer I don't want to do this for obvious reasons.

You are tackling this issue very handily and learning a bunch. Congrats.
On preventing the mask condensation, one goal is reduce moisture, but another trick may be designing a mask cozy. If you mostly insulate the exterior of the mask, then the cold air temperature of the room won't reach the moist air (or not as well). gluing felt or other insulation to the exterior will reduce cold contact. BEWARE covering engineered leakage ports will negatively affect air flow, and more particularly, the exhaust of exhaled CO2.
Also, there are cloth liners that you can place between your mask springy cushion and your face. they can provide some added controlled leakage to wick off moisture similar to tissue, only somewhat self-drying, and can stand multiple uses.

I recently changed my CPAP settings and have been sleeping a lot better. I also made some tweaks due to condensation inside my mask not rainout in the hose that leaks to mask but condensation.
Anyways, I am seeking feedback on my current settings , can anything be further improved? As I am still getting day time sleepiness despite my overall sleep improving as I am not waking up 4-5 times a night now.

Your median pressure was 7-8 cm, i.e. half of the time, you needed higher than that pressure.
Your 95% pressure was 9-10 cm, i.e 5% of the time you needed higher pressure than that.
Hence, if you do not want to be disturbed by pressure adjustments at least 95% of the time in the evening, you should have a minimum pressure of 9-10 cm .

The latest posts show there is some, small, amount of OAs, some, small, amount of H. Increasing the minimum pressure from 7 (might) show a decrease in those numbers.
Since you see snoring aligned so well with flow limitations, a pressure adjustment would make sense.
The machine likes to adjust when the OA and flow limitations are occurring, and those seem to be at time when your pressure is under about 8.0 to 8.4. When your machine reacted to the first set of events, the pressure vaulted to around 12, but what if you could prevent those occurrences (which were happening when the pressure was still about 7.0 to 8.0)?
It makes some sense, therefore, to pick a minimum pressure of 8.6, to skip most of those environments.
Thus ends my version of learning opportunity.
Hope you get more restful sleep now that most of the condensation has been whipped!
