I've seen them done with anywhere from one to five jumps, but it sounds like Beanie is definitely the experienced one in this!
Unfortunately. Ugh.
ETA: I should not say 'ugh,' it's not fair to Auggie. We had a lot of challenges but we learned so much. Really I am blessed to have had him as my first agility dog. It just doesn't always feel like that!
My trainer doesn't do jumping work either and I think it's a mistake. After everything I have read and learned about jumping, I truly do believe it's a super important skill to teach our dogs. I did baby Salo stuff with Payton and Georgie both early on and, like I said, because it's so boring and as humans we want to hurry up and do "real" agility, I have done less and less over time and I really NEED to do more.
I have done both Suzanne Clothier's jumping program (Naturally Jumping book) and Susan Salo's jumping DVDs. I like both of them for different reasons. I have never picked up Mecklenburg's book, I believe there is at least one person on this forum who has done it (Shai maybe?) so I can't speak to that one. I know competitors who use it and like it, I just don't know the details.
Clothier's program is nice because it lays everything out VERY clearly. Week one, day one. Week one, day two. Week one, day three. It's basically a calendar that you follow. You need a total of ten jumps for her program, starting with five and then working up to ten (you use two together to make an oxer - a jump that is as wide as it is tall.) The first several weeks are pretty boring because it's just about teaching the dog rhythm. I have a playlist on my YouTube channel with a lot of the Clothier videos:

(Rather boring videos. No fun to edit either.)
Once you have the rhythm down, she takes you to a troubleshooting phase where you start to space the jumps out differently and introduce things that make the dog actually think about his jumping and take-off point and such. At this stage you see the dog's jumping break down again, then improve as they start learning. It's interesting stuff and I like the theory behind it. I really did a lot of this with Auggie and he seemed to really enjoy doing it too. If I left the jumps set up in the back, he'd run back there when he was out to potty and start jumping through the chute. My mom took him outside one day and the jumps were all put away, and he paced around by the fence crying because he wanted her to set up the jumps for him. =P
I also have some Susan Salo videos up too but not as many:

Most of these (if not all) are actually filmed from the side, which IMO if you can film your jump work from the side it's better than working from the front. You can see a lot more of the little things in jumping style from the side.
I really like the Salo exercises, but the problem I have is everything isn't laid out super neatly in a "this is what you should do when" kind of formula, so I start floundering and struggling. For these I think you only need five jumps. She also likes you to use different jumps and different LOOKING jumps (in her DVD she's like "Put a flower pot in front of the uprights, now you've changed the look of the jump!" so it can be very simple stuff.) I did kind of work out a schedule with these that I worked with Auggie, but since he is retired I don't really remember what it was like. I did a lot of googling and found some people's notes from seminars and worked something up. I think I have my jumping notes in my training notebook at home and I can pull it out and see.
The most common one she does is the set-point exercise which is done with two jumps, though I frequently do a similar exercise with only one jump... basically without the stride regulator. When I warmed him up on the practice jump at trials, we did almost exclusively set-point-esque jumping. These also did not seem to be as "fun" for Auggie to do, but he definitely learned things from them. I got a leg up on a LOT of competitors with difficult courses because Auggie became a master at being able to slice a jump super tight. I could set him up on a start line with a tight slicing angle and basically run a straight line with him, while other people are throwing in crosses and trying to get a good lead out so they can handle. I'm thinking of three courses right off the top of my head where stuff we learned doing Salo jumping made a course super easy and other people struggled and even bombed on it.
I like both programs, but if I only had to pick one, I think I would go with Salo. Clothier's jumping program is a bit outdated and a new version has been "coming" for years. Part of the problem is the world of agility has changed as far as the kind of courses judges are putting out. They used to be smoother with wider spacings, but that was "easy" so now they are choppy, tight spacing, twisty-turny. I've seen people on Facebook praise courses that are basically built to completely prevent the dog - or the handler - from getting any real flow, because they're "hard." Personally I think the increasing difficulty in agility is why you are seeing more dogs struggling with jumping, because what we're asking them to do is not very natural and difficult for them to do. And I think Salo's program is better suited to the more recent types of courses. But I do really like them both and I'm glad I have both, because I've learned a lot from both programs. Of course, Clothier has a book that is like $15-20, and Salo involves a DVD set that I think is $40-50... and there's both foundation jumping AND an advanced jumping DVD. =P LM has both a book and a DVD series if I remember right so that might help. I do wish the Salo stuff was in a book, because I like to be able to take a book into the yard, look at the book, and say "okay THIS is what we're doing and it looks like this." I took notes from the DVD so I have something to take, but it's not nearly as nice as if it were a real book with pictures and stuff.
Hopefully somebody else can chime in about LM program specifics!
