Interleave is a tradeoff... improved error correction vs latency. If you are going to use a digital mode, as an Amateur, you have a responsibility to learn something about how it works. For the general population, software needs to be "idiot proof". This shouldn't be a constraint for software used by Amateurs ;-)
