On the surface, this seems like a stupid question, but here goes:
When it comes to HR monitoring, how good is "good enough"?
I cannot be perfect, so at least once a day, and often more, my HR exceeds my AT. I have learned to very quickly remedy the situation, but I wonder if that's good enough. Over time, I've lowered my guesstimated AT from 120 (yeah, I was clueless then lol) to 95, which has definitely reduced my crash frequency and duration.
What was your experience with this? How perfect were you and your daughter?
I was more perfect than my daughter.

I had to be because I was sicker and couldn't recover from overdoing as well as she could. I got so that I could go days, or even weeks without going over my AT, but I had some help around the house in those days. If you're doing all your own cooking and shopping, that may not be possible.
I had to develop a lot of strategies to stay under my AT. I walked around the house with that step-pause-step-pause bridal walk because anything faster put me over my AT within 10-15 steps. I only went up stairs once a day and had to sit for several minutes halfway and again at the top. I only showered a couple times a week and then sitting down. I couldn't towel off without going over my AT, so I got a giant terry bathrobe to wrap myself in and crawled into bed immediately after the shower -- another necessity since once I showered, I couldn't do
anything else that day without going over my AT.
What I used to do standing, I started doing sitting -- cooking, dressing, showering, etc. What I used to do sitting upright, I started doing with my feet up -- paperwork, reading, watching tv, eating meals.
If my alarm (set below my AT) went off, I sat down right where I was -- stairs, middle of the floor, whatever -- and waited until my HR was back to normal. Not everyone has to do that, of course. I just found that once my HR started climbing, it shot up rapidly and stayed up unless I took fairly extreme measures.
For me, spending more than 10-20 secs above my measured AT would result in some degree of PEM. I learned to stay below that no matter what. To accomplish that, I ended up setting my alarm 10-20 bpm below my measured AT and stayed below
that number. I found it wasn't just a question of not going over my AT. It was also about not spending a lot of time near my AT.
I thouoght about it like this -- the average healthy person doesn't walk around all day with their HR at 180-190 bpm. Working up near your AT is an exceptional situation even for a healthy person. They do it during heavy exercise, not routinely. So why should we PWME be trying to function near our AT all day? Being near our AT should be reserved for the limit of our activity and done infrequently and only when necessary. For me, that was taking a shower or getting back upstairs to my bed. Otherwise, my goal was to stay far below my AT for routine activities, which is what a healthy person does. My sister doesn't jog in place the whole time she's cooking dinner, do jumping jacks at her desk, or run full-speed through the grocery store.

Why should I ask my body to to the equivalent?
Yeah, my house got dirty and I had to break up my meal prep into many 5 minute increments throughout the day. But I got better, so it was worth it.
