As you say, it's just difficult to tell, the tile loss seems less dramatic than many used to expect back when the heat shield was relatively early in design, but ultimately only SpaceX knows how much they're passively losing during the coast phase. All I'm saying is that that's one more factor besides relight that I think will need to be sorted (it might already be sorted, I wouldn't know) before orbit.
