Still 630. Adding mswiz777's 477 because of a very good Correlation workup. Here is the (highly experimental) Correlation Workup that sold me on mswiz777's 477:

I see there are plenty of other numbers there from 2017 which haven't been touched yet, but that 477 really looks good to me.
As always, remember that these stupid charts of mine make it look inevitable that a number is going to fall when that is simply not true. They very probably will not fall, but it wouls be very cool (not to mention profitable) if they did...
