Personally I can’t get past the fact that RO has the highest interest by far, yet lower BO than TFA and TLJ (and even on cumulative interest it’s still quite a bit higher, as is ROTS, over TLJ, despite the ultimate BO performance). Point being, it seems like a rather imprecise science, especially considering there isn’t the full picture for TROS yet.
And again, I have to ask, who cares exactly? Why bend over backwards to make a prediction when we’ll literally know how it’ll shape up in a few short months? Despite your protestations, it’s hard not to think you want TROS to fail.
