I'm not discounting your experience guys, I'm just wondering what is really happening when a ski meets the mountain. If the real world is real, then someone should be able to prove it somehow.
Think of all the other variables that get thrown out of the discussion.
Are there any analog situations that are easier to measure and could inform the discussion?
Has anyone ever attempted to measure different setups empirically?
How about a double blind Ski tune challenge? Three identical pairs of skis tuned differently, three different riders, could they tell which one has the 1.5 degree base?
Does a ski edge really get hardened by grinding it? Is it really that hot? Has anyone ever measured it?
Can you harden an edge by skiing over a rock? If so, how is happening, heat? Impact?
So many statements make me go hmmmm? All these squishy words that get used to describe what's happening, but no data.
And of course - HUMANS! They're mostly unreliable witnesses.
NO one said they could tell a 1.5 from a 1. Or a 2 from a 1.5. That is not the point and really serves no purpose.
What I am sure I can tell you with a high degree of certainty is which ski has more or less base bevel comparatively.
Don't need no stinkin' data........I've tuned it and skied it! 'Nuff Said!
Have you ever tuned a ski yourself???
If not I understand your bewilderment! If you have tuned, then I can't understand your bewilderment.
Or maybe your ski skills are such that none of this matters anyway???
I love the guys who have never tuned a skis and can't ski worth a sh_t, who get on here questioning what experienced skiers know to be true FROM EXPERIENCE!! Now I don't know you so I don't know if this applies to you
Next you are going to tell me that strings, string gauge, the string pattern, string tension, racquet weight and balance, and construction material of my tennis racquet all make no difference cause I can't prove it to you with an equation.
And by the way, I thinkyour calculations could be inaccurate. A 1 degree base edge bevel creates a 1MM gap 60MM across the ski when a truebar is matched to the edge angle.
So the difference between a .5 base edge bevel and a 1 degree is .5MM 60mm Across the ski!
You are calculating how much P-tex is removed to flatten the base of course depending on existing base discrepancies not to bevel the base edge!
