One should also factor in that it's not just the engine that's being broken in, but also the drivetrain. Lastly the manufacturer limits the car and recommends you follow the break-in period as stated in the owners manual. Notice for the break-in they don't specifically mention the engine, but rather moving parts in general.

He does not say the method does not work with synthetic - he says synthetic makes it very hard to break in properly
"Synthetic oil is so slippery that it actually "arrests" the break in process before the rings can seal completely. I've had a few customers who switched to synthetic oil too soon, and the rings never sealed properly no matter how hard they rode"
and I'm not aware of any limits BMW put on an of my M cars I have had during the first 1,200 miles. (2008 M5, 2011 1M, 2017 M2 - all with manual trans)
and finally, the OP is talking about doing pulls with the engine....
