@Raptor: Have you observed changes in jump mechanics from what you see in scooby to what you imagine as appropriate mechanics in you or others with help of what you suggested? If so, did those people have the years of jumping experience like scooby already has under his belt? In which time frame did those changes take place?
Well for me, off two feet, I'm jumping much quicker (and higher) right now than in the past. Not sure what the cause for that is but, other than the increase in strength, I think the two leg bounds really did their magic for me. They just improve the intermuscular coordination, if you're lacking in that, and also make you accept much higher levels of tension in the plant without making you stiffen up and blow the jump (which is what was happening in the past). The jumps are more relaxed now than in the past (basically I just exert tension when I need to and then relax and allow my body to "elongate" (triple extend) properly, whereas before I would just continue to stay stiff and just "block" myself out).
So I think it's important for scooby to do some multiresponse two-leg bounds and some consecutive hurdle jumps and film those, and see how well he does them. See if he's "not sure" in his consecutive jumps (takes time to reset etc) or not. Stuff like that.
As long as time frame is concerned, for me it took, I don't know, a month of plyos or so to see some effects.
