That doesn't make those "UK-style IFR in VMC outside CAS" logging entries retroactively wrong or illegal, but just means you cannot use them as credit towards the license conversion.
I don't see that. For example, I did my FAA IR when I had 125 (+40) hrs. Since that time I have flown numerous flights IFR on an IFR flight plan, but also I have bimbled around in UK Class G IAW IFR....Therefore surely that Bimbling can count towards the hrs rqd for a conversion if I so wished?
