Around 750 feet on hard surface with 6,600 lbs gross in clip#1, 2:45 onwards https://www.twitch.tv/videos/2722275938

1,500 feet at 5,500 GW on hard surface in clip#2 https://www.twitch.tv/videos/2722275940

In this clip#3, around 2,100 feet at 6,500 GW on soft surface (I know the igniters are set-up wrong)

Full beta+max brakes are used on all clips.

There is a huge difference in clips 1 and 2. It may a "sim thing", but from user point of view, I'd like to know what is going on.

Am I seeing correct performance in these clips?

For which parameters is manual's 400 ft ground roll stated for?

On the technical level, how does the model "see" the runway surface & friction coefficient? Do scenery's surface type and surface texture matter?

In this clip, the parking brake does squat. It is a 2020 scenery. https://www.twitch.tv/videos/2740655772 (Forgot to trim the clip, the beef is at the beginning).

Are there any aftermarket high performance brake kits for these birds, hehe?
