You must be cutting it fairly close/short, if longer clippings are
left on the lawn, thatch does build up.
The secret is to keep the grass about 2 1/2 inches tall, never
letting it get mich over 3, so you are never removing more than 1/4 to
1/3 of the blade at any one time.

Nonsense! The point is not to cut off too much.
Isn't that what I said??

I set my mower as high or higher
than it goes and it works fine.

I think the point of mulching is to chop the grass up until it is small enough
to filter through the remaining grass leaves until it doesn't get sucked up
again, so it doesn't show when you're done.

You are correct.
