default values have no effect ? [BUG]

[Avatarsia]

i saw that video on youtube, show your script, very nice work!
https://www.youtube.com/watch?v=8d49_QUmP9k&t=895s

i installed and run it, and got the same result's recommended Accel=78350 & Velocity=1339.
i was totally wondering about this values based on the fact that i know these values are too high.

i just entered [auto_speed] in the printer cfg at this time

when i add more options to the configuration it became more realistic
i used now

[auto_speed]
#axis: diag_x, diag_y ; One or multiple of x, y, diag_x, diag_y, z

margin: 20 ; How far away from your axes to perform movements

#settling_home: 1 ; Perform settling home before starting Auto Speed
#max_missed: 1.0 ; Maximum full steps that can be missed
#endstop_samples: 3 ; How many endstop samples to take for endstop variance

accel_min: 1000.0 ; Minimum acceleration test may try
accel_max: 30000.0 ; Maximum acceleration test may try
#accel_accu: 0.05 ; Keep binary searching until the result is within this percentage

velocity_min: 50.0 ; Minimum velocity test may try
velocity_max: 700.0 ; Maximum velocity test may try
#velocity_accu: 0.05 ; Keep binary searching until the result is within this percentage

#derate: 0.8 ; Derate discovered results by this amount

#validate_margin: Unset ; Margin for VALIDATE, Defaults to margin
#validate_inner_margin: 20.0 ; Margin for VALIDATE inner pattern
#validate_iterations: 50 ; Perform VALIDATE pattern this many times

results_dir: ~/printer_data/config ; Destination directory for graphs

now the results are:

recommended Accel=23516 & Velocity=549, and these also survive the Validation

so could it be that there i a wrong default value take effekt that i get the same values with a total different mashine ?
