It is a rule that could be increased, although I doubt it in Pedersens case.
Also not sure where the 1.6 conversion comes in as people state, when the 2019 rules state it was 1.5 for 2019.
16.2.6 AMENDED MA’s have been amended with the Approval of the BSPA GC or Directors for:
a) Riders who have been absent from British Speedway racing for more than 3 seasons (NB. The MA may be increased or decreased).
b) Riders who have been absent for more than 1 full season due to injury.
c) Any rider who has been or is eligible to compete in the NDL (and has not represented another FMN, other than the ACU) will receive a 2.5% reduction on their MA.
d) a rider who moves between the Premiership and Championship leagues and requires a converted MA, the conversion factor will be 1.5
