Yeah, but they should also send a new job immediately on seeing a new block. Unless of course there are some strategies they use to detect how to react to blocks from different pools. Might be interesting to uncover 
Thanks for that link to the data. We don’t see the pool name there, right? Do you think we can include that for the data from now on? Or it might be in another data set somewhere that I can join. We want to get the pool names for the orphan blocks too.
Sorry, am new to all your work, so probably asking naive questions.
EDIT: Just this: Offer: Stale block dataset
