Anyone running a Quarq Dfour power meter with Rotor QXL rings? Any fitment issues getting the QXL rings on?

According to Rotor's information, the QXL rings are compatible with Shimano 4-arm 110BCD cranks, so should be ok with the DFour.

Quarq has not yet released its non-round chainring compatible firmware for the DZero or DFour, so any measurement will be inflated by a few percent. As far as I'm aware, they just need to increase the polling rate to account for small changes in angular velocity.

It is, but I haven't heard a date or even a timeframe.
