I've always preferred a finish gate for one big reason - it drastically decreases "clockwatching" while approaching the finish, allowing more time for looking out and finding/avoiding conflicting traffic while planning how to merge into the pattern. And since you knew that you could finish either high or low, you could have a plan for each case; if high and in traffic, stay high; if alone, push over and finish fast and low; if really low, call a rolling finish and squeak in. Done all of them, and never worried about losing points by being too low, or trying to ooch over an invisible line in the sky...



Now with flarm, getting surprised by someone at the finish should be rare..



I do see the potential problem of a lot of finishers at the same time at a small field - which is where a cylinder makes sense to give everyone time (altitude) to sequence for landing.



But at a big field with lots of landing room - perhaps some brave CDs should try some gate finishes (perhaps tied to -gasp! - a speed task) and see how pilots like it.

That's an interesting point Kirk.

For those airports with one runway and you can't land a bunch of gliders line-abreast, I've been thinking about the new GP start (BTW - thanks to BB for coming up with an elegant and flexible approach to make that happen). Judging from observations of GP contests it seems like you might end up with most of a class finishing in a narrow time window (start as a gaggle, fly the task as a gaggle, finish as a gaggle). What do you think is a reasonable amount of altitude buffer to allow, say 12 gliders to land within a few minutes on a single runway? Do we need to abide by the "one airplane on the runway at a time" rule or do people land in formation like the Thunderbirds (notice I didn't say Blue Angels)?
