Gotta love how the Core Rulebook says "Here's the rules to see just how high and far your character can jump." and then it doesn't list any rules for vertical jumping. Let's fix a fix and make it better. Check out my math, these rules are as close to realistic jumping rules as you can get while staying simple.
Changes can be summed up as: "You can do a running jump equal to your yards in M. Standing reduces this by 2 yards and takes a half action, doing a long jump increases it by one and makes you prone. First rank of strong legs adds a yard not a foot. Elves count as 2 M higher for jumping."Changes can be summed up as: "You can do a running jump equal to your yards in M.
