Correcting Time Estimates?

Greetings! 😃

I'm currently experiencing a little bit of a problem regarding inaccurate time estimates with my prints - They finish on average by a â…“ faster than what PrusaSlicer predicts.

The Machine Limits used to calculate the print times represent what is set in the Printers Config file ( Feed Rates, Acceleration, Jerk ) but the times are what I'd describe as kinda whack:
Print I expected 4h15min vs. result 2h53min
Print II expected 2h20min vs. result 1h34min
Print III expected 7h59min vs. result 5h13min
etc...

I did some calculation on those times and they're in the 65-68% range so about a â…“ Overestimation of the actual time it took to print the parts.

Screenshots of the Print and Printer Settings:

Printer Config:

[input_shaper]
shaper_freq_x: 71.4
shaper_type_x: 2hump_ei
shaper_freq_y: 40.2
shaper_type_y: mzv

[printer]
kinematics: corexy
max_velocity: 300
max_accel: 4800
max_accel_to_decel: 4800
max_z_velocity: 30
max_z_accel: 350
square_corner_velocity: 3.0

Somehow, I'd imagine the printer running slower than the simulation given that the Print Settings has sections running slower than what the machine is capable as a whole but here it's the exact opposite? 🤨

Any suggestions on how to fix that? 🤔
