Yeah I’ve heard that, think we’ve discussed it before, I read hot mode was every 172 bonuses on average (don’t know where I read it and can’t find the link) and DOA is every 151.
It seems to add up (even if the sample size is small) I had 3 on Happy Holidays by 393 bonuses, so four across both games by 619 (or 647 if you counts ones on HH since last Hot Mode) bonuses. Or maybe I’ve just been very lucky!! ?
