not necessarily as a "always delay before playing" sort of thing but more a short description of how it works,
I agree! It's always better when the user actually understands *why* they need to do something.
In general, though, I would advice everyone to consider a delay between "open" and "start" when you design your patches, in particular if you plan to distribute it to other people.
[open <f>, start( is convenient, but it can be hard to refactor at a later stage!
Personally, when I build a playlist in Pd, I have one or more [readsf~] objects and cycle between them. For example:
| cue | readsf~ 1 | readsf~ 2 | | ---- | --------- | --------- | | 1 | play 1 | open 2 | | 2 | open 3 | play 2 | | 3 | play 3 | open 4 | | 4 | open 5 | play 4 | | 5 | play 5 | open 6 |
etc.
I think you get the pattern.

*This* is a good point and worth noting, not necessarily as a "always delay before playing" sort of thing but more a short description of how it works, then a note like "if you experience occasional dropouts on first accessing a file, consider adding a small delay after opening but *before* playing."

Actually, I forgot something important:
Of course, the worker thread must also *open* the file! If the file is not yet cached by the OS, this can indeed take a few milliseconds.If you don't add some delay between "open" and "start", you might notice that you get a dropout the very first time, but not on subsequent times.
In fact, if you don't wait between "open" and "start", the perform method almost certainly blocks. However, often we don't notice because it may be "absorbed" by Pd's own ringbuffer (= "Delay" in the audio settings).
Anyway, I agree that the help needs some more clarification! (Just make sure you really understand how the object works before changing the help patch :)
