Continuing on, what is surprising is that Tyzer can do the exercises laid out there, it's these he has problems with:-

The jumps have been moved to the more usual UK setup ie straight on and Tyze takes the pole down on #4 almost every time. The gap between #3 and #4 is enough for him to get up some speed and he'd rather get into his poles asap than sort out the jump.
So we stopped and rewarded #4 a few times and then tried back chaining with no success, as soon as he gets up any speed he goes through #4.
So we're going back to basics, working 1 jump, doing figure of 8's around 1 jump and then beginning to ramp it up a little. Criterion for reward - jump the jump 7 times without touching it. This he finds difficult and so it's what we're going to be working on for a while. It shows that although we've worked turns and sendaways, I've neglected to work on duration as far as his jumps skills go.
So thanks to Stuart Mah!
