When you use power tools and are working on many DIY projects, it is imperative to make neat cuts and work ahead as per your needed measurement. however, even if a miter saw has a throat insert panel or not, it is very much sure that ultimately the overlapping bevel will give away from the closed aid. This point has been highly amplified and is somewhat quite true.
There are some precautions to be taken - When a miter saw leaves a cut, it can be very beneficial to have an "auxiliary table" in place so that the cuts won't damage the wood. however, if the plan is to make two particular cuts at unlike settings, the space of the two cuts will fall apart. Anyway, you can always expect help to one side.
Therefore, saving a cut is as important as making the cut itself.
