"Meaningful" logbook entries

[eye_in_the_sky]

I am curious to know what standards people use in their filling in of logbook entries.

For instance, a quick tour around Melbourne.. is that

"YMEN - YMEN" or
"EN - EN" or
"EN - airwork - EN" etc ...

I would also be interested anybody notes the class of operation of the flight, eg PVT, AWK, CHTR or RPT.

Cheers !
