Alright,
@ChiefD
I wore the watch tonight for my tempo run. First of all, I actually looked through all the options ahead of time and set up a training workout for what I was doing tonight to gave it a shot. It was a 45 min tempo run that is supposed to have 10-15 of slow running to start, then slowly build until you get 2/3rds of the way through the run and peak at 10k pace for 2-5 minutes, then back it down and finish with another 5-10 slow minutes. After a 10 min warmup, I set it up as 5 min intervals with a :15 window for pace (i.e. 5 min of 9:30-9:45, then 5 min of 9:00-9:15, etc. with a peak at 7:45-8:00).
--That was really interesting to run with the watch telling me where my pace should be. I've only ever used it to record my data and HR and to look at pace and/or HR during a run. Using this trainer, If I was too fast (which is usually what happened, especially at the beginning of each 5 min), it would buzz and then gave me an indicator when I was back in the pace zone. After a couple times, I got used to it. It completely took the thinking out of the run. I can see pros and cons with that but overall not bad.
--It was humid AF out there. I was completely soaked 5 min into my run. Despite temps in the 70's, it did not feel good to start.
--I only looked at my HR at the very start and it was reading 120's. That didn't feel right at all based on how I felt (mostly with the humidity) so I just stopped looking for the rest of the run. Not surprising to look after my run to see it jumped all of a sudden to 150 halfway through my 1st mile. I would have guessed I was 145-148 to start which is probably right where I was. Still, not bad for my 9:40 pace in that humidity.
--I got to my peak pace and was getting into a groove. Working a bit, comfortably uncomfortable, nice open stride, and enjoying that part of the run right next to the lake. As I'm at my peak rate and getting ready to back down, this woman running toward me from the other direction slows down to a stop and flags me down. Now, there's lots of other people around (mostly people either walking or sitting by the lake). No idea what's going on and why she's stopping me. She's mid to late 30's, like an 8/10. So I stop in order to figure out wtf she wants (do I know her?) and she goes "do you know how far it is around this lake?". Are you freaking kidding me? I'm running at a pretty brisk pace and she stopped me to ask that? Now, I mapped out a route from where I started that was a total of 5 miles but there are all kinds of ways you can go so I have no idea where she's trying to go and I've never run around this lake before. I tried to give her an approximation and she's like "well, I've already run like 2.5 miles and still have to get over there". Finally I just shrugged, said I was sorry, and started back up. I was so annoyed. If she wasn't relatively hot, I'd have been downright pissed. If you look at my Strava feed, right around 3.2-3.3 miles in, you'll see a dip in my HR where I stopped for like 30 seconds. Ugh.
--I hit that tempo run just the way I was supposed to. My average HR of 162 isn't that bad for that kind of run I suppose. Pretty pleased with it overall. I wasn't feeling it at the start, that's for sure.
--After the run, I started trying to set it up and sync with my phone and Strava. Next thing I know, all of my wife's runs from the last couple months are getting added on my Strava account. No!!!!!! So I just spent the last 15 minutes going through and deleting those. All for you,
@ChiefD 
Too cheap to buy a new one (particularly with a decades-old habit of manually recording my workouts).
