4 passes is way to much for the neck.
I personally never do more than 2 or 3 passes for the neck. And then it's just BBS. But if you say you had to do 4 passes to get a decently smooth neck shave, sorry, then it's your technique or blade.
Give your neck a few days to heal. if you don't heal you'll end up with razor bumps.
Try with another razor. See what it says. That's going to be the only way for you to know, really. And we have to be sure it's a properly honed blade too.
We should be down to 2 variables. Now it's just a matter of eliminating one.
