Why stop at buddy checks. Why not have a third party come in a check. Why not fourth person checks?

How is your buddy checking you better than you checking yourself a second and a third time? Would two self checks equal a buddy check? What about three?

I check everything I do. I then check it again. I don't NEED a buddy check EVER. If I did then I shouldn't be climbing.

Am I infallible? No. But my failings aren't things that a token buddy check will pick up on.

If I am THAT worried about "redundancy" then I would climb on two separate alternating single ropes with independent belayers and backup belayers. Sure we can always improve safety, but 'buddy checks' are well down the list for me.

Nobody is proactively discouraging buddy checks. And nobody is stating that a "better" way to check is up on a route.

I have a simple rule to check my own knot when I reach down to clip the first piece and consider this the best habit to get into.
