Time between ovulation and the pre-lay shed

Time between the pre-lay shed and laying
Most people say the average time between a female's pre-lay shed and actually laying the eggs ranges
from 26 to 30 days, including two of the most popular books by big-time breeders. When my first clutch
was laid by a female 48 days after her pre-lay shed (with much freaking out on my part), I wondered how
accurate this range was.
The following is a histogram of the time between a snake's pre-lay shed and lay date, including data
from my own collection and others'. Twenty measurements are shown (some are for the same snake but
different breeding years). This is much different than the usual consensus! If the outlier
snakes are removed (48 and 51 days), the mean changes slightly: 33 +/- 4 days. A more accurate range,
then, is about 30 to 40 days after the pre-lay shed, not 26 to 30.
One snake in this list (not included in the 20 count) did not shed at all between ovulating and laying.
Thanks to Bob O'Brien, Sue Anderson, Pamela Trentham, and Michael Losoya for contributing data to
