Comment (by adamsilverstein):

 >The most common scenario for preloading is for render-blocking resources
 which might appear after the first HTML network packet (as they would be
 discovered a full round-trip later by the download scheduler), as the
 earliest moments are the ones when there is more network bandwidth
 available, due to less competition.

 > Preload directives should not be used for non-render-blocking elements,
 as then they would compete with the render-blocking ones slowing down the
 render.

 Makes sense, thanks for clarifying this!
