Your data shows the true "long pull" levers (the Gevenalle CXV0/Tektro RL520...) and the Avid Speeddials set to their V-brake setting do indeed have a lot more cable pull and lower mechanical advantage than any of the caliper brake levers. The caliper levers do vary a bit in pull and mechanical advantage but, except for a couple of outliers, are in a fairly narrow range. I can't see any of them being unusable with any of the current or former brake caliper models.
