I think most of us would agree on "raw data" being no FD or map display in use, i.e. no guidance other than bearings (non-precision), displacements (precision) and the rest of the standard flight instruments (AH, ASI, ALT, VSI...). A percentage would add the criteria of AP and/or AT out, although "manual flight" is distinct from "raw data": you can have neither, one, the other or both on types that I've flown.
Item 3.9.3.1 is a mandatory item for LSTs (and ATPL upgrades) and reads as follows: "Precision approach down to a decision height not less than 60m (200 ft)', manually without flight director".
Interesting, that one, as I work for one of the larger UK airlines and we don't check that. Manually, yes, but w/o FD, no. We've been on ATQP for the last few years so that adds to the confusion.
However non precision approaches have to be flown from the database...
We don't have that restriction but can't go lower than circling minima without the AP engaged on a NPA.
