Do you mean the construct of probabilistic speculation applies in multirepo because you may end up with a hot spot repo that receives a high volume of commits at once?

Or do you mean that multirepo could also benefit from the construct of probabilistic speculation by ordering commits across multiple repos such that you are maximizing the number of repos that have changed before you build and minimising the number of commits applied to single repos?

Or both :-)

the former actually.

If you have 1 app that's the bread and butter of your company and, 60% of your 2000+ engineers working on various features of that one app, then even in a multi-repo world, you are going to have that 1 repo receiving ton of commits and the problem of keeping it green remains. Prob. speculation helps there.
