Yes, now you've said that (Noggin) I can see it can be read both ways in GID 33.
GID 33 talks about those expired over 5 years "will be required to meet refresher training requirements as determined by the Authority". It then says what the MINIMUM required by the authority will be... x,y,z.
I interpretted that as 'we the authority will decide, but brace youself for at least x,y and z and maybe we'll decide more...".
Indeed, as you say, it could also be read as 'go ahead and just do the following as a minimum plus whatever else the CFI says'
Although the latter might be preferable, and hopefully it does mean that in pratice, it doesn't fit exactly with the earlier 'the authority will decide'
