mechanical relay switching lifespan, switch cycle durability (version 2)

Using the various datasheets from omron panasonic TE hongfa etc,  the below plots are obtained/estimated. using 1A resistance load as a common point of comparison,  there are generally 4 durability categories quoted in most makes cycle life of 100k 200k 500k 1000k >2000k all lines are plotted vs the background of omron 274P/234P,  most lines are expected to be y = 1/x positive curve like the omron,  or in the cases of TE they are y = -ax there is already an expected trend of how durability / wear works,  however HFD2 appears to follow different physics rule, t he curve follows a y = -ve parabola HFD2 pdf also does not define Temf parameters most entry level relays would reach EOL (electrical) at 2 to 3 million ops,  the mid tiers would reach around 6million+ ops,  the real beasts go 10million ops easily,  and then there is the reeds which normally play in the 100 million+ ops range,  and the solid states in excess of 1billion.
