If we have about 100 cases today, and that doubles every 4 days, we'd have about 60k cases in 37 days.

    (6 + 31) / 4 = 9.25
    2 ^ 9.25 = 608
    608 * 100 ~= 60k

When I wrote "6 + 31 days" I meant "6 (initial) cases, 31 days later". I thought that was clear in context.

Ah, yes `6 * 2 ^ (31 / 4)` is much larger than 100. Good point.
