maybe worth getting YAFU to testsieve algebraic vs rational when the estimated norms are close together?

I think it does that, when yafu is testsieving I'm quite sure I saw it doing a test for algebraic side.
Maybe the large difference I found was caused by various factors, cado vs msieve, optimized vbcurtis parameters etc.
What also brings a nice boost is starting at much lower qvalues, instead of 60000 I now start at 10000 which for some numbers had 50 rels/q while at the final q it was about 15 or 16. Maybe it's advisable to go even lower.
