I seem to recall "in the old days," there was no mid-phase "check" given on the line, it was administered in the sim. If you went to a different seat sometime in your first year (i.e., 727C--> 727 B), that training eval counted. This relatively new "mid-phase" program seems better for all involved and the use of an AQFO/LVP is better for Captains because it ensures it is a validation of the F/O and not a checkride for all.
