I do this fairly constantly for GNFS as I work through aliquot sequences.

It looks as if 28-29 is at about C148, 29-30 is at about C153, and 30-31 at about C158. But it's a reasonably subtle effect and there's about 10% noise in my measurements simply from sometimes sieving a bit too far. Here are some high tide marks

Code:
CPU-hours  size lp
284.9  C139  29
288.5  C140  29
334.9  C142  29
342.6  C142  29
359.6  C143  29
422.0  C144  29
452.9  C145  29
548.4  C146  29
713.8  C148  30
762.8  C148  29
768.4  C149  30
823.6  C149  29
899.3  C150  30
1038.9 C150  30
1100.6 C152  30
1206.6 C153  30
1341.4 C154  30
2500.2 C157  30
