Hotend Heating Testing Protocol question: New mk3s+

Prusa Testing Protocol heating measurement times, Graph doesn't match reported time

I just opened by printer and it included graphs of the temp for the hotend and heatbed.  I was concerned that despite saying the hotend passed by heating to 250c in a time of 2m 30s, the included graph showed a time of over an hour (1h 1m 36s) to reach the target temp for the hotend and was wondering if that was a normal reading and if it would take that long to heat up once assembled or not.  How exactly is that graph generated and why is it different than the reported passing times?

The generated testing protocol sheet also was torn right across that reported time so not sure if there was just a problem and instead of addressing it someone tried to hide it in some way.  Don't mean to be suspicious but it just concerned me.

Best Answer by JoanTabb:

Doesn't it say Target 250C reached in 1 minute 36 seconds?

Here's a picture of the printout, thought I had included it in my last post but it didn't show up.

Maybe, looked like 1 h 01min and 36 seconds to me but perhaps the tear made me read it incorrectly.  I didn't think it could heat up in a minute and from the syntax of the other one it made me worry.  Sorry for worrying I will just put it together and find out!

Welcome to 3D printing... 

where the obvious isn't always so obvious, and our intent on doing the best job that we can sometimes introduces unexpected concerns
