Hi Cyrus,
Yes it's interesting that these figures have not been published by the SFA yet and they are not in the recently published TTG and Apprenticeship guides.
However, they are in the LIS and this is what they are (in LIS18.01)
A 1
B 1.12
C 1.3
D 1.6
E 1.72
F 1.4
H 1.2
J 1.25
K 1.5
L 1.15
(Thanks to Rich Eaton at New College Nottingham for extracting these)
I also see in the YPLA Funding Rates and Formula v2.2 that they have published the PWFs which are the same for A to F and then they have rate G 1.92 for (Specialist resources). At least the two agencies haven't assigned different rates to the same letters.
