I have a MKII and have left it cocked for an hour or so a few times. I don't think this makes a difference or causes any unnecessary 'wear', but thought I would put it out there to see what the consensus is.
All springs wear. I say never ever leave anything cocked as it's a accident waiting to happen. We're only human & can easily get distracted.
In addition to the mechanical wear issues mentioned above, the majority of air rifle safeties are simply poorly designed. A safety that blocks trigger movement, even at the sear level, does not prevent the hammer from being released by the cocking piece that holds it. One reason the Taipan Veteran is such a great field rifle, it can be de-cocked with a pellet in the chamber, and will not double load regardless of how many times it might be cocked and de-cocked. Until the rifle is actually fired, the mag will not advance. The HW100 can be operated to do the same, you just disengage the slide that engages the gear that advances the magazine, but you have to remember to do it. For the most part, my rifles are not cocked until I'm taking the shot. Exacerbating the issue, many of us adjust our triggers for minimum sear engagement and light spring tension. If you assume that any safety can fail at any moment, you won't be far wrong.
If you are able to be absolutely cautious, if you have an electronic trigger you can have a pellet ready to fly always and forever.
No fatigue is possible.
But the possibilities is an accident increase a lot.

I don't know enough about the electronics to have an informed opinion. But I would not be comfortable carrying my Red Wolf with a pellet chambered. I would be afraid of accidentally disengaging the safety, which would leave me with a very light trigger until the system timed out. And if I got a shooting opportunity, and found the safety off, I might be confused enough to double load it. My use of the RW is almost exclusively from the bench.
