Some writers make two or three revision passes through an MS and are content.
Others turn into endless tweak machines, fussing with grit, grinders and polishing cloths.
I have no idea if the different approaches have anything to do with whether they are pansters or plotters.
And it doesn't matter - except when a piece has gone to formal edit.
That's when the Tweakers must put a sock on it.
Imagine the unadulterated joy of an editor - half way through an MS - who receives an e-mail from an author stating s/he has completely revised the beginning and added a chapter.
Seems there are writers who even make anxious attempts to introduce changes in a work after it has gone to copy edit.
Hold those brilliant additions until your editor has gotten back to you.
Respect the process.
