Well, not really- it's likely Ryan wouldn't pay attention or have a go at it until something near t55 was done.

If you don't want to use the Bayesian tool each time you queue curves, you can still improve on the old methods by doing half the usual number of curves at a B1 level before moving to the next B1. Once you've done half a t50, move to B1 = 110M, etc. The second half of the effort for t50 is then completed by the 110M-bound curves,while improving chances to find bigger factors.

~2*t50 is enough for C167, so t55 is more than enough.

4 days for a c146. <===> 4000 days for a c197.
(Just to keep things in perspective.)
