Interesting post.
If it is the 747 simulator, try this one. Full or as much power on the brakes, before you go skipping and get the sim instructor to fail an outboard engine and see if you keep it on the tarmac.

I'm a fan of the skids marks at the brakes release point that swerve towards the side of the runway.
Tee emm is correct about folks pushing more and more throttle lever while the motors are lagging behind. If it's already lagging why do you think pushing the power lever forward will help? As doubleu-anker implies, good luck keeping it on the runway if you get a large power split.
The best skid mark to view that is Cancun (CUN) Rwy 12. Main gear skid marks come within feet of leaving the runway.
Another is MIA Rwy 08R. FO thought it was from someone turning onto the runway too fast but you can see where the nose tire skid marks start on the runway centerline stripe.
JFK 31L had a differential N1 skid mark, it faded over several months/years, so someone replaced it with a new one.
Never understood how the skids marks were produced until I saw it happen. Full left nose wheel while the a/c shudders and bounces to the right with smoke billowing from the nose tires!
FO and I were speechless.
