Default Why delete the history?

I've gone over many tutorials and many times they tell you it is important to delete the history. But they never say why?

So, why?

Maya has to calculate each history item you make in the sequance it was made. Once you start getting a bunch of them, the model can become unstable. Also, some actions, like binding and animation, can be adversely affected by some kinds of history items.

Are there any hard-coded rules as to when you delete the history? You said that some actions, like binding and animation can be " can be adversely affected" by the history. How would I know when this occurs? Or should I always delete the history when before I start the animation process?

I guess I"m looking for some rules as to when to and when not to delete the history.

I always delete history before binding. I also freeze the transformations, to get rid of any affects to transfroms and scales, etc.

There isn't really any set rule that I know of for when to delete your history. Just know what when you do, it's effectively "baked" into its current state, so only do so when you are happy with a model at that state.

For example, if you smooth an object to see how it looks smoothed, but do not want to keep the smooth, then you would not want to delete history, as then the smooth would be permanent (barring undos, of course).
