Q:Avoiding excess geometry and bunching edges...
 

I was wondering how do I best address issues as shown in the attached image on future projects.

The image shows 2 areas I chose to simply collapse edges to a single point rather the extand geometry down the entire length of the model.

Is this acceptable?

Is there a convention or some rules on handling things like this?

Also called "kite faces" or "diamond faces".

Thanks Mike!
