So........ anyone in the yellow and red areas of the United States noticing that they are playing softer reeds to get everything to work fine? And I mean ALL REEDS both cane and otherwise. (today is the 5th of June 2024)
In a related question. I am in the yellow area (roughly 700ft of elevation), using reeds (Legere Sigature Soprano Sax) that are a full half strength softer than normal and the barometric pressure for me is 29.68 inches of mercury. I could not help noticing that currently, the barometric pressure in Cusco Peru is 29.83 inches of mercury, which is still low but it is HIGHER than mine and Cusco Peru is sitting at an elevation of 11,152 ft.
Is that seemingly odd barometric pressure result for Central US vs. Cusco Peru normal for this time of year?

Yes. Philadelphia suburb; current pressure is 29.73" but we have thunderstorms on the way, so I imagine it will drop.

Thanks so much Karl.
I wanted to (once again) reference this video (all amazing but.....) that states (starting at 34:14) WHY we need to have a variety of reed strengths available to us. Eugene Marquis talks about the weather, which I found mind blowing because outside of cane being more flexible when damp I cannot say that I've EVER heard anything in a reed lecture, class, summit, masterclass, regarding weather's effects on reed performance.
I have just Googled enough to find that there is a difference between barometric air pressure and static air pressure (what you feel at Base Camp Mt. Everest). At least now I don't feel as if the Earth has just been knocked off orbit!
However, if someone could comment on whether "STATIC AIR PRESSURE" changes sometimes (I am currently having a very soft reed time these last few days that started BEFORE the barometric pressure moved down, BEFORE a rainy front came through 06-05-2024.

Maybe you could use a divining rod to point to the best reed on a given day. It should detect the higher moisture level.

Your questions are legitimate Paul.
My attempt at humor with my attached "product idea," I assure you is my attempt to laugh with, not at you.
"Boveda: our hyperbaric chambers and humidity pack kit now regulates humdity AND pressure."
I'm still working on the external speakers to transit sound outside the chamber for concerts.

.....and.......
you bring up an interesting point.
There is no need to worry about the humidity in your space vs. the hall you're going to play (given the same city). It seems that much like the barometric pressure and the static pressure, your reeds play within the prevailing dew point (effective humidity). I found this when my indoor humidity happened to still be "off the charts" high, and yet the reeds were being subject to the slight barometric change at the time which was in negative territory. What seems to be happening there it that the air molecules of the room (house, building, etc) are eventually knocking against those of the outdoors, so if THOSE are moving less advantageously (low humidity equates to denser air) than there is just less movement. The chamber becomes irrelevant.
