The Beyond Einstein Reach of LISA Is Almost Directly Proportional to Mission Duration

In particular for extreme mass ratio inspirals: 1. The constraints on post-Newtonian parameters tighten with increased duration. 2. The chances of an especially favorable case increase with duration. 3. The chance of multiple confirming cases is proportional to Mission length. 4. The signal to noise for plausible inspiral candidates continues to accumulate significantly well beyond five (and even ten) years. (See Barack and Cutler gr-qc/0310125). The currently proposed duration of five years is more than adequate to place significant constraints on post-post-Newtonian parameters, but they become tighter and possibly extend one further half post-Newtonian level if the mission is extended to ten years.
