Actually, that's a common misconception. When "jump_off_a_cliff_ratio" is set to a value other than "-1", then "jump_off_a_cliff" is ignored. The ratio is divided by 20000, so if you set it to 10000 your system will only jump off a cliff if 50% of friends do so.
The default setting is "15000", but some distros change it (e.g. Arch sets it to "0" so that your system always jumps first--more performant, but less safe).
Conveniently, none of this is documented anywhere, all the other information you can find online is years out of date, and most sysadmins just accept the risk of cliff-jumping rather than trying to tune it manually.
