Question for SnapRaid Users

Can SnapRaid restore the a lost drive in the case where the other data drives have been written to since the last sync? My understanding of the principles is probably just lacking, but I worry that using parity based on the other drive's data would only work if the data on the other drives had not changed since the parity was last calculated.

So do I invalidate my last sync as soon as I write new data to a drive in my arrray?
