Same here.

I spent just under 4 hours grinding this plane. I also had about 40 minutes travel tine and I wouldn't have spent the time to use a machine that is designed to do one thing which is to remove metal if I thought I could use sandpaper and a piece of glass to flatten it. I know every body thinks they can flatten a plane but iron doesn't sand like wood
A machine can do the work with precision controlled by the operator. In your case it gives the added benefit of 90º sides.

Using sandpaper on a flat surface takes a different knowledge and skill set.

A plane with a slight convexity can end up worse when worked on by someone pushing it over sandpaper like a rocking chair.

In my limited experience I've seen a few planes with badly flawed soles brought into useable condition with a calculated use of sandpaper.

To tell the truth, if I had the machinery it would be my preferred method.
