A final thought about reciprocity failure with paper negs.

The more I thought about this the more I realized that, with very long exposures, the risk of overexposure is lessened by reciprocity failure, and the longer the exposure, the less the overexposure risk. In essence, it is far easier to fatally underexpose than fatally overexpose, and far more efficient to overexpose and then work backward from that than vice versa.
