[BUG] Min Cruise Ratio Setting Interferes With Results

[mbrady4597]

Describe the bug
A clear and concise description of what the bug is.
A minimum cruise ratio setting >0 in the printer config may result in higher accel values from the test because the top speed will be limited for short movements. More testing may be needed to confirm this issue in different circumstances. It should be an easy fix to slightly redesign the test or null the min cruise ratio setting while running.

To Reproduce
Steps to reproduce the behavior:
Run auto speed with min cruise ratio of 0.5 as is default and then with 0.0

Printer (please complete the following information):

• Printer: Vcore 3 400mm
• Kinematics: CoreXY

My config settings:
[auto_speed]
margin: 20 ; How far away from your axes to perform movements
endstop_samples: 2 ; How many endstop samples to take for endstop variance
accel_min: 20000.0 ; Minimum acceleration test may try
accel_max: 150000.0 ; Maximum acceleration test may try
velocity_min: 200.0 ; Minimum velocity test may try
velocity_max: 2000.0 ; Maximum velocity test may try
derate: 0.9 ; Derate discovered results by this amount
