I've read in a few places that the values of text strips is not exact because of the warm-up time for the bulb. However, since it is just a test strip, I'm not sure of the need to account for this. Has anyone quantified how much less dense the darkest portion of a test strip is compared to a straight exposure for the same nominal duration?

When I am making a fine print, I typically make test prints 1/8 stop lighter and darker than the final target and, after everything has dried completely (overnight, if not longer), I judge whether the target density is what I really want and adjust accordingly.
