Upon looking more closely at my workouts from the weekend I am seeing erratic data and some random extreme spikes in stroke rate and pace that don't make sense and after reading the firmware update logs I presume they're probably due to bugs fixed in later releases. I've been researching a bit about how to update it but most of the stuff I've found is people having issues updating it via cable, so I'm a bit nervous to do this without more guidance.
So my questions right now are:
1. Is the update likely to be successful so that I could do this myself via my iPhone or should I just ask the staff about it? –– they're mostly students too so I'm not sure they'd know much more than I do right now or even care, but at the same time, I don't want to mess up the machine because it'll be out of order for months if that happens

2. If I were to do it, is it quick enough that I'd be able to use the machine within 30 minutes or does it take several hours? Does my phone need to be by the machine for the whole time or does it download the data first to the PM5 and then update itself?
I'm not sure if I'm being silly and just overthinking it but I'd be grateful for whatever advice you guys can provide. Thanks!
