Infinity war was $258M, BP was $202M (for the Thu-Sun period each). I think current projections have DP2 around $150. But, those really are just educated guesses. Pre-sales are usually factored in, but not usually from all sources of pre-sales. So, for example you might have pre-sales for Fandango or something, but not all pre-sales for every other company. So it's useful as a comparative reference but it's still open to so much variability.
I think Solo opening at $170M at this time of year would probably be a number Disney is happy with, though not overjoyed, but it all depends on how it fades. TLJ I'm sure faded faster than they anticipated.
