You don't have to target each 'algorithm' all at once. You can target them one at a time. Hell you can run A/B test single out the easiest targets.

Yes but right now there is 100% of the users using the one algorithm (or chronological). If one doesn't know what percentage or which people are using which algorithm, it becomes harder to know which ones to try to hack to have the biggest result.
