An AAVA is voluntary
People will be required to do iFacts training, i.e. not voluntary.
The only other way round it is for people to be scheduled do training on their normal watch days, then AAVA the shortfall!!
Although I think the money being talked about is incredulous (bearing in mind AC ATCOs already get a very good deal with the amount of AAVAs they get offered per year etc), I do think that the rate should be higher than AAVA as it is a required attendance on a day off.
