The extra step is still in flux. I've tried it with a great deal of success to my own ears, but Modulor will be testing it himself and deciding whether or not it'd be worth his extra time to incorporate it into the next batch.
Those with the first batch of Modulor pads could in fact do this step themselves if they are somewhat handy; it is a very destructive and permanent step though. The cool thing is with the way Modulor made the jergpads, you won't see this extra step visually.
And again, it's in flux still, meaning we could still possibly improve it in some way.
