The closest precedent is Danny King.
As he was an asset of neither league it was decided that as Birmingham owned him as a top league rider then Coventry got priority over Ipswich.
If Frost owns the assets outside the structure or if being held by BSPA then Id imagine top league would get priority as they were bought as top league riders.
The team total was around 47 in last years PL so using Holder at 1 in place of Josh G is the 3 point swing to the new 2017.
That is the reality of what the league is this year - just a touch above last years PL.
Generally if you replace a No7 in the new Championship with a 'top' No1 you will have a Premiership side.
I see your point and that lower limit will be in place it seems but I was looking at a different point.
If a side were to lose each of their first 4 away matches by say 20/30 rather than 10 then the redeclaration will have more flexilbility whatever the limit is.
With a 'brand new' average being acheived from those first 8 meetings rather than a rolling 20 the impact of any reduction would be greater.
In the PL he also partnered Danny in 3 of his heats and ended up with more bonus points than any other Witches rider last year.
For Ipswich after a shaky first few weeks he was generally exceeding expectations.
