Not in the context of the OP. It's a good drill, since seeing (or not seeing in this case) is believing for some
I'm just curious what distance it is, since 50% of people fail at the lost line drill

Really? 50% fail lost line drill?
I have done one.
In the Chamber of the Ancients, in downstream Carwash, you run a long primary reel in to the mainline. That mainline forms a small circuit, and the two ends of the line are about four feet apart, and easily seen at the same time. When I did the circuit and got to the end, I was facing my own reel, tied into the other end of the line. I could literally have put my knees on the end of my line, and my hands on my reel. Rather than go back all the way around, we went forward and picked up our reel and left. I suppose that a sudden total siltout might have caused problems at that point, but I had three lines (both ends of the mainline and my own reel) within six feet of me, and you'd have to work very hard to silt out the entirety of the chamber.
Other than that one occasion, I do not do visual jumps and I marked all intersections . . . unless I'm narced (right, Rob?).

I don't do visual jumps. Considering I only get to cave dive about one week a year, I figure I need all the practice at running jump lines I can get ...

I think Dive-aholic is getting students to go from one line to another in a silt out? Which is different to how I did lost line. Just had to find the line I had been on.
Well that's what I thought
Does anyone see a difference between jumping back onto gold line to close a circuit, like TSandM did, and visually jumping to start on a tunnel?
Visually jumping back onto a continuous line vs jumping onto a line where you might have to turn around and not have a continuous line.
In other words, it seems possible to make a visual jump while maintaining a continuous line to the exit. As dangerous or less?
I do not condone anyone making visual jumps.
