Don't make chapters about a single point that is fully expressed in a three-word sentence. Don't be afraid to make chapters about multiple points or developments, it makes them even better (note: while not impossible to find, the pattern is mostly the first one). Don't always put the main point at the end (note: again). Regarding that also, don't tease all the time for its own sake, reveal things more often instead of teasing them first to let people wait a week or more. Revealing should be more fun than teasing, and more important. For that, also refer to what was previously said about multiple points and developments. Don't stretch things for its own sake so much, or delay them for some imaginary schedule and time scale. Respect the readers' time (which is lifetime), and have the readers' enjoyment in mind, more than some tertiary principles about teasing and the right date or duration for a (sub-)arc. If a story can be told more quickly, but at the same time with more things happening at greater density, so be it.
Something along these things is what I think all the time...
