Go where the yield is best -> 50-280M looks better, since the yield below 60M looks thin (compared to yield at 250M).

I think you meant to make the lims 268M rather than 26.8M.

Thanks for the catch. This should have been an easy 31-bit job but I couldn't get a decent yield. Back to the drawing board.

I propose Two Golden Rules of 14e queue parameter choice:
1. Choose lim's such that your forecasted sieve range ends before 2 * {lim on the sieving side}. You don't have to choose a power-of-two lim: 140M is not a fast choice (just above a power-of-two), but there's nothing wrong with using 180M or 100M.
2. Choose LP bound such that average yield (specifically, relations divided by Q-range) is 2.0 or higher.

It's really unlikely to go wrong when following these two rules, and rarely faster to violate either of them.
