I'd only partially agree with the second point if applied as an always rule, but I'm also not the guy landing loads of kills just yet
I'd restate it as staying higher most of the time while making your prey loose E and/or watching for their mistakes is generally wise, but sometimes other approaches pay more. A slice attack angle (from a lower alt angle) is sometimes a better option and other times (against planes that can hold a tighter AoA for longer) all you may be doing if you wait for them to come up is following them around all day as they turn under the majority of your passes.
There's a weird, fluid sweet spot between being too aggressive and not aggressive enough, we've all witnessed this in our own successes and failures as both the bouncer and the bouncy. If we can learn to read where that spot is in our relative situation we'll likely play our cards right and end up the victor. Pardon my spelling I'm very tired and typing from my slow iPhone.
