How often should one reset base angle?

[Wilhelmson]

If you measure your base angle you could ever so slightly shim the base guide to take off a minute amount of material to expose a fresh sharper edge. Might help, might not.

By the way, if you see the Head racing team ski tuning class video on YouTube, official Head rebels ski service master, Alex said that he always uses the auto machine to set the base bevel and doesn't touch it at all but very fine stone polishing job sometimes. He said " I don't do it because I'm trust the machine more than my hands..."
Well, I still like to touch both side of the edge... my bad

Not to mention he gets free skis and all the best equipment.

I do the base edge once a year at most. Basically when it should look and feel smooth. If it isn’t you probably can’t really get that ski sharp.

So true. Auto machines changed the whole situation. Minimum material loss with the best result.
And... he doesn't need to pay 100$.

If the edge gets really round, you can’t just sharpen it from the side anymore. So, increase the base bevel or get the ski reground.
