Just need some "sub" encouragement

[who]

So I have subbed once before and succeeded. Temp strip on the outside, swished, etc.

I have to do it this week and I have been practicing for a week.
3oz shampoo bottle, double boxer briefs with the bottle in between them (so not to burn the taint, lol), temperature and everything.
I have practiced over and over, I am just nervous because I read a couple people not having temp strips on the cups.

I have the heating and cooling down to a science. I heat on the car heater until 110. At ten minutes, it's at 103 and takes two full minutes to get to 98.6 swishing and cooling. I have the spread written down from 110F starts from 5 mins crotching to 45 minutes crotching, and all the final temps and cool down times to be within "range".

In reality, I am just nervous if there is no strip on the cup. It will be a Labcorp.

I have done this before when my first was dilute, and I succeeded with much less research.

I am wigging because this job is double the pay I was getting, and obviously very important. I think it said on the paperwork that it's a DOT test, I will be in a car on runs, but it's primarily a desk job.

I just want to see that checkbox ticked and I NEED to see the strip light up to feel better and secure. I am not even happy for this job yet.

I know some people get thermometers that are silent, and I am considering it, but that's one more thing to potentially drop.

Advice, wisdom, encouragement?
Thx

PS - I read the subbing sticky and am very familiar.

Dont let this worry you.

Just keep your sub bottle at 100F. When you do pour the sub in the collection cup, a temp drop is expected, particularly when liquids are transfered from a warmed container to a container of less temp. How much the temp will drop depends on how cold the empty sample cup felt before you poured your sub in. If the sample cup feels quite cold to the touch, I always "prewarm" the empty sample cup by tucking it in my armpit as I close the bathroom door, unzipping, etc.

Just dont spend unnecessary time zipping up and leaving the bathroom to hand over the sample to the collector, so the sample temp doesnt drop out of the proper range of 90-100F.

I have tested with 100 and it drops too fast for me and hovers around 94. I have to be prepared for up to an hour holding - 30 mins is the average wait I have read. So 110 works well for me and naturally drops while crotched to 99.5 after 30 minutes, then 98ish at 45 mins.
If I get out of my car, signed in, and in the room in 10 minutes (which is fast), it will be at 103 and will take 2 minutes to cool to 98.5-99.

I feel safer with it hotter as my little scientific experiment has proven that this works best for my body (starting hotter that is)

I have practiced with no temp awareness, cooling and counting down, then temping as if I was in the room with no strip, and I did fine.

I would just rather cool it than be stuck.

Thanks for the encouragement, logic tells me to chill because there WILL be a temp strip. Paranoia sets in, then I get nervous.
