Some assorted questions about tracking -current

Hi,

I've been running OpenBSD on my laptop for a few weeks now and have\
been having a pretty pleasant experience. I've heard of the current\
branch of the operating system and I think it'd be fun to check out\
with the added benefit of having a few ports I want that aren't in\
the release builds yet. I have a few questions regarding this:\

1. Are these builds stable enough for daily use outside of testing?\
My laptop isn't exactly a production machine, but I would still like for it to be able to be turned on every day with minimal fixing-\
effort. That doesn't mean I'm against fixing the occasional bug,\
though.\

2. How often should I upgrade/jump to the next snapshot?\
I read on the FAQ page for the -current branch that upgrades are\
handled with the syspatch -s command. How often is standard to run\
this? On my rolling Arch gaming rig, I usually update about twice\
a week, but I assume that the number is different here, because\
OpenBSD is a different operating system.\

3. How are major upgrades handled?\
When OpenBSD 8.0 comes out, will I have to do any extra work to\
keep tracking -current, or will it just keep rolling on and on?\
I assume you can call -current a rolling release...

Thanks,
Ethan
