Cura 4.7 print times way off

[ADmakes 0]

Started using 4.7 a few days ago.  On the 4.6 version my print estimation times were always within a few minutes of actual print time. 

I noticed my first few small prints printed much faster than 4.7 estimated, like 20 minutes to an hour faster, on 2-5 hour estimated prints. 

Finally did a bigger print last night: Cura 4.7 estimated 11 hours 36 min

Actual print time: 7 hours 38 min. 

This is on an ender 5. 

 

it seems the estimates get further off with longer prints.

 

Im glad the actual print time is faster than the estimate, but it was pretty accurate in 4.6 and I would rather have it be accurate. 

Im mostly posting this for the Cura developers, as I dont think there is anything I can change to make it more accurate. But if there is let me know, thanks
