Anecdotally, I have certainly found that although the cost in time may not vary as much as this table would indicate, the cost in stress ramps up even faster. Fixing a bug in production is usually a highly stressful endeavor for all involved. I would love to see a similar table phrased in terms of stress comparing different development methodologies currently in vogue (test and throw it over the wall, CI, automated pushes vs. manual pushes, etc.)
