I'm strictly chronological - can't cope with jumping around at all!! Some people are linear thinkers and some aren't - fascinating!

I know novelists who write the way you do and their work always appears to be seamless when it's finished. I think that's down to good beta/editing.

Even a linear writer like me sometimes has chunks that have to be rewritten (e.g. because you suddenly discover anachronisms) and then you have to read the whole thing through to make sure there are no clunky transitions. One of the problems is repetition - feeling a need to explain something, whether it's a description or background, or whatever, and then you find you've done the same in the bit you were rewriting/inserting...
