I've been doing a lot of counting leaves/internodes between clusters on determinate and semi-determinate plants this year. What seems to be common, is that the plant will do a "termination sequence" ie cluster - leaf - cluster cluster- leaf, and after that it will start again with either (a) the number of leaves before the first cluster on the main stem, or (b) the number of leaves before the first cluster on the side shoots, and then the termination sequence is repeated and the shoot terminates.
So I also noticed on a couple of plants that there are a lot of adventitious roots forming, right around the place where the new (a) or (b) series begins. As if the plant was shooting off another 'plant' of itself, to root down into the ground.
So if I wanted to root a shoot from a determinate plant, I would count the leaves between the clusters, and I'd make my cut at the bottom of a series of three leaves or more without any clusters between em.
If there's a cluster below and you want those fruit, leave one leaf just above the cluster and make your cut.
