Lifespan per Initial Population (abbreviated L/I), also called evolutionary factor previously, is a measure of the quality of a methuselah. This measure was first suggested by Don Woods under the name of "age to initial size".[1] For example, the R-pentomino has an L/I of 220.6.

As it only relies on initial population and not on the methuselah's bounding box, it is considered inferior to L/MCPS (Lifespan per MCPS).
