Great - thanks for the link. Time to update the bookmark!
Pity to see no changes to Section A Appendix B, though, to give some kind of definitive answer to the question of how to log time when a qualified pilot flies with an instructor, for example for a club checkout or a currency check.
Since neither the table in LASORS nor any other written source I can find contains advice for this particular case, I shall continue to advise my students that I will log P1 and they ought to log PUT to be conservative, even though the less conservative option of PICUS seems far more logical in many cases.
