Tbh buddy it doesn't really matter if its split the instability is down to the exploit itself yes running it over and over can cause a kp the problem is we need a more reliable webkit and a more stable exploit^^ as i said before, they have to be splitted, because the kernel exploit cause KPS very easy. In fact, a tip for kernel exploit... wait 1 or 2 minutes after entering webkit, and you will see how the Kernel Exploit will always get entering without KPs...
In my experience the best thing to do is switch on the ps4 and let it boot properly
Treat it like an old pc/laptop from the 90's
When you think about it a ps4 is basically a custom pc it's got a cpu/gpu/ram/wifi and a slow old mechanical hard drive
If people stop treating it like a super fast pc with a lightning fast ssd
You will get a better success rate
And tbh run the exploit once load all your payloads and just use rest mode
