How would multiple wagers on “Maturity” work? Let’s say… 3. Would it be additive and instantaneous (increasing points by 30%) or would it be done in steps (increasing points by 10%, then increasing new points by 10%, then increasing the new point value again by 10%)?

I expect it would increase everything all at once. So five wagers would be a 50% increase

I would expect 5 10% increases that compound, since it’s being applied 5 times in sequence.

Yes, the rule for Spinning the Wheel is to “Apply the Payout of the Marker, to every Gambler for each time that Segment appears in their Wager”, that reads like a sequence of five separate applications.

Self-kill on further reflection.
