+                    //
+                    // 2) Giving the raw execution times is misleading since scripts start at different times, making
+                    // it impossible to compare scripts.
+                    //
+                    // 3) Scaling the raw execution time to the time that the script has been running is better but
+                    // is still misleading since a script that has just been rezzed may appear to have been running
+                    // for much longer.
+                    //
+                    // 4) Hence, we scale execution time to an idealised frame time (55 fps).  This is also not perfect
