Table 1.

LL (larger-later) peak time, spread, and maximum peak rate for each SS (smaller-sooner) delay and estrous cycle. Note that the LL delay was always 30 s.

Delay	Phase	Peak Time (s)	Peak Spread (s)	Maximum Peak Rate
5 s	Proestrus	29.7	21.5	0.32
	Estrus	28.5	21.9	0.31
	Met/diestrus	31.4	21.6	0.33
10 s	Proestrus	29.9	19.5	0.38
	Estrus	29.1	19.8	0.36
	Met/diestrus	31.2	19.9	0.39
20 s	Proestrus	30.3	15.6	0.51
	Estrus	30.2	15.5	0.45
	Met/diestrus	30.9	16.6	0.50
