Having done this recently, there does not appear to be any associated stipulation as to what is done, other than the fact it is. Record that it has taken place as appropriate in log book and have it in the training records for any CAA inspection.
The main points have been covered.
Mass & Balance Z chart & calculation.
Fuel and potential unusuable in event of boost failure.
Start modulation of fuel, but keep it at the hot end of the start range.
Selective loading
Different engine to 206B2/3 (generally but not always) - when testing anti icing TOT reduces generally rather than increasing.
The only other area I add is if the L1 is also IFR certified, in which case there is a whole lot of other avionics on board/ force trim/ stabs etc.
The flight manual I have for the L1 is quite a bit thicker than the B2/3
