The way I see it the red rtl crosses the top of bar 7, OB, so black pt2 is outside it.I see that, but if you mean the whole up tape as b2b2r2b, the b2b is within the prior tape's RTL. No issue with that? And what about containers for the up tape, don't care... you only see the need for b2b2r2b, don't need 3 BBTs for the up tape, each having its own FTT?
I'm not familiar with the "equal weight" approach.
I see the black up container I drew as a tape.
