I've experienced the same discrepancy between Chitubox's default exposure times and "The Cones of Calibration" with my Saturn printers. However, on my printer the "Cones" required a longer Exposure time than Chitubox's default setting. A representative from Elegoo did tell me that each printer could have slightly different light intensities and it might be necessary to use a longer exposure time on one machine when compared to another (I own multiple printers and was expecting them to all use the same settings - which they don't).
Any time I have a print that uses a lot of the Build Plate's area or is tall we need to use a longer exposure time. Our Bottom Exposures are typically around 10-15 times the Normal Exposure time. Long Bottom Exposures could cause a small ridge to develop around the bottom of the prints where theyy touch the Build Plate. Also, the resin will have an influence on Exposure times. My Saturn S printers average somewhere between 2.5 seconds when printing 28mm figures to 3.5+ seconds for a terrain piece in that same scale. An Exposure time of 3.7 seconds doesn't seem too out of line if your piece was heavy or thick.
Resin type and color does have an effect on the exposure time - whenever I print using black or dark gray resins those exposure times have to be longer than the time for a light gray or white resin of the same type.
Hope this helps
