Question about ReWire implementation (for the Renoise devs!)

Hi, I am not sure if this is offtopic or here,

But I have a question for you Renoise devs. How are the ReWire transport requests (play/stop/position) that are sent from Renoise synced to the mixer DAW? Is there a formula that compensates the time between issuing a pattern restart and the end of the RWDEFDriveAudio call? Or is the position just set to 0?

Much love,
Maxim
