From what I read, the 11002 is an interline chip and does not suffer from Residual Bulk Image, so RBI flooding is not needed. I guess that, if the chip is vastly overexposed, there could possibly be trapped carriers that need to be cleared by a read. If the camera works OK on following frames, do a quick read before exposing frames that you want.
