The advice remains extant - check with the CAA!
"I am considering joining a syndicate flying Jodel D-9 reg G-****. Please advise me whether hours gained on this aeroplane may be counted towards the CPL qualifying total"
Make sure that you include the registration to make clear that the D-9 in question is a SEP Class aeroplane, not a G-M*** class Microlight aeroplane.
And don't use obsolete terminology such as 'Group A' when writing to the Authority if you wish to appear as though you know what you're talking about, I would suggest...
