LPC-826 graphs

I have an LPC-826 in a pocket mini conservatively running at 325mA. Though I've already LED'd a LPC-815 and a LCC red from heavy use (built about 3 years ago) I'd like to see how long this diode will last under the same usage rate.

I prefer to build within the limits of heatsinking in the host, that's why I selected the relatively low current for the build. It has an old Meredith Red lens and outputs 223mW. The host warms slightly when it's running for several minutes.

I just finished this LPC-826 build with a lot of copper sinking and a 478mA driver getting 319mW.

This diode has been here for a while, so has anyone ever made more accurate graphs, possibly even analyzed the bell curve for diode variations?
