On the first point: "the multiplier for the rating of 1899 (12x) would be applied." (the 'payout' rating vs. actual rating)
That's great- will save me quite a bit in SPS rentals!
On the second point: "@clayboyn had an very interesting idea" I would hope that it would be Proportional, Transparent and Equivalent in regards to applying a level multiplier bonus- although, given the history of such things in SPL, I don't have high hopes.
