Re: time taken using a cordelette vs. tying in with the rope
Hi,
I've timed this on a number of routes with a stop watch (and that really does make me a geek).
1. there isn't much in it.
2. with two climbers who know what they are doing tying in directly is faster.
3. with three climbers, two of whom don't know what they are doing, a cordelette often faster.
The main question is: will you be belaying directly. If the answer is yes, then an cordelette is the natural way to go, and time isn't the key question. It you need a powerpoint for the belay plate, then you might as well be tying into the powerpoint with the rope, rather than going back to the anchors.
If you are climbing in a three on a multi pitch route then you almost have to use the belay plate in guide mode as otherwise the seconds won't be able to climb at the same time and still be safe and hence you will waste a lot of time.
It is also worth considering what happens in a three if you want to rotate the leader when climbing on double ropes. If you tie in with the ropes to the anchors you will have to do some serious faffing to sort the ropes out. It would be much better to clip into the powerpoint with cow's tails, untie and swap ends.
Final point (honest), one of the main reason for the whole cordelette/reverso in guide mode/both seconds climbing a at the same time thing is the synergy within the approach AND that it means you DON'T tie the seconds into anything! You just leave them hanging from the plate. Job done. (Always place a backup knot.)
Does that make reasonable sense?
