Is it important to keep the rounded shape exact? or is the height the important part?

The rounded shape is important if you want maximum saw performance. Some operators just use a guide and leave the rakers with a flat top. This creates chain vibration, and additional friction which robs engine power. It doesn't matter if you have many horses to play with like on a Lucas but chainsaws usually need every pony they can get

This Vid shows how I set my rakers - of course I don't do this every time. I only set them like this occasionally. In the field I swipe them freehand.
The main thing to look at it how I file them to get the rounded shape - it takes a bit of practice but then it gets easy enough.
