Right, but again, what's the True Goal of jump part of athletics? Unlikely it's "achieve maximum at vertical jumping with these very specific conditions". It's more like "achieve maximum at vertical jumping". Which includes thousands of variantions. It's just we can't measure it without some standards, so specific rules were introduced.

I'm not sure I'm familiar with racewalking story. Any good links to read?
