My water is sitting at 58 deg F. Did a CYA test and sitting at 60. I can’t remember if this test reads optimistic or pessimistic in cold water. I’m not going to wait until the sample warms up to room temp.

If you don't want to wait for it to get to a higher or room temp, I'd be cautious about how much CYA you plan to add based on that.
Go slow, is all I can say

Yeah I get that so am I looking more like 40/50 or 70/80….?If you don't want to wait for it to get to a higher or room temp, I'd be cautious about how much CYA you plan to add based on that.

You'll want 70 once the water is warm enough that the SWG is working, and 80 once the TX heat shows up. You have 80-84 degrees Monday and Tuesday but then it cools off for the rest of the extended forecast, so you have at least that much time.
My cya test read high when the water was cold. I was reading closer to 70ppm but when i let the test sample warm up, it showed a more realistic 50ppm.

At cold temperatures CYA testing reads low.
At colder temperatures it will take the solution longer to precipitate.

Don’t know if it’s wrong or right, the first thing is I fill to the first line in my Taylor kit’s cya test bottle, cap it and put the bottle in my pocket as I do the other water tests. Then after all other tests are done and I cleaned up, I put my digital kitchen temp probe in and the sample is often like 76, 78 degrees. Then I add the cya reagent to the next line and run the cya test.

This is a great idea! - don’t know why I never thought of it since i have used this method with ear drops for years. Cold ear drops suck !
Ohmygosh. Why didn't I think of this before? I could slip it into my "girl pocket" (shhhhh, my bra) while doing the other tests.
Skippy once showed me how soldiers put their MRE hot dog packs in the front of their fatigues....short time later when he opened it it steamed! (Pre-heater pack MREs)

This is good to know. Can we get the water temp effects on CYA added to the Extended Test Kit Directions?
Thankfully I’ve been holding off adding stabilizer since my pool is 57 dF now.

Never mind 
I reread the Extended Instructions.
Taylor Technologies has run the pH, total alkalinity, calcium hardness, free chlorine, and cyanuric acid tests on known standard solutions at approximately 104°F, 75°F, 60°F, and 40°F. Only at 40°F did the CYA standard solution test higher than its actual value (after accounting for test variability). All other tests were unaffected by temperature differences.
