For three days in a row, the sales ratio between SS and JB on Movietickets.com has held up very well compared to the actual gross ratio.
Monday: SS to JB ratio on MT was 4.55. The actual 4.48
Tuesday: SS to JB was 4.9. Actual was 4.76
Wednesday: SS to JB was 4.19: Actual 4.09
I had guesstimated SS to gross 8.7 to 9.3 based on an assumed gross of 2.1 (30% drop) to 2.25 (25% drop) for Jason Bourne.
Obviously, when there are two unknowns, the key is to guess the more predictable/less volatile one (in this case JB) to set up the projection for the more volatile one. The soft drop of JB threw my Wednesday projection off. But the SS to JB relationship on MT held.
As of now, the sales ratio is 21.2 to 6.8 = 3.12 The relationship b/w SS and JB seems to have been altered due to the entry of Sausage Party on MT. Otherwise the SS gross on Thursday would be around 7 Mil., based on a 10% drop for Bourne. That seems too low.
