Spinning Wild Mouse brakes inconsistency

OS: Windows 10
Version: v0.2.0-101
Commit/Build:0oec3ccd

The brakes on Spinning Wild Mouse are inconsistent. The break values seem to be randomly changing between 2 values.
It's been like this in the past year and a half i've been playing on OpenRCT2.

Steps to reproduce:

1. Build a Spinning Wild Mouse ride with 3x pieces upward into a downhill 3x pieces into a break.
2. Complete the track.

If F is lesser than or equal to V then V = X
where:

• F is the value of the brake set to,
• V is the current speed the car goes into the brake track,
• X is the new speed the car slows down to when running through a brake of F value.

example:

A Spinning Wild Mouse car (1 car/train) is running on a Hyper Twister track.

• F := 28 km/h
• V := 37 km/h
• then X is either 19 km/h or 27 km/h

A Giga Coaster car (1 car/train) is running on a Spinning Wild Mouse track.

• F := 28 km/h
• V := 37 km/h
• then X is either 19 km/h or 22 km/h

I don't know if this is a bug or it was intended.

Screenshots / Video:

Start by reproducing the listed Spinning Wild Mouse setup on Windows 10 and compare the brake outcomes for the two example cars and tracks. Trace the brake-speed calculation used during the run; the issue is done when the inconsistent values are explained and corrected or confirmed as intended, with a regression check for the reported cases.
