Oh I see new conditions now but, after 25 years experience with control valves, and comparing that to your is it two weeks experience with your first softener, - I can tell you that it is rare for Fleck or Clack valves to have wear problems regardless of how frequently they operate.
The piston travels in seals made of industrial grade materials and only move slowly up to 1.5" and back during a regeneration of normally 90 minutes or less. Backwashed or regenerated filters that operate daily use the same parts and materials although the piston has a slightly different side view shape and there can be fewer seals than in a softener and the wearable pars last 10-20 years. And then it is usually something in the water that causes a build up on the edge of the seals or on the piston between the seals, in the spacer area, that causes the "wear". When there is iron in the water, you use Iron Out or some other type resin cleaner and it removes any build up the iron causes.
Well, I know how you don't think Aquatell puts out valid data, but perhaps you might put more merit into it than info coming from a 3-week old "softener expert" such as myself. But THEY seem to think that frequent regens speeds up the wear of the valves... http://www.aquatell.com/knowledge-center/understanding-true-water-softener-capacity Read Paragraph 3. in blue, near the bottom...
All those years in engineering school musta been wasted, if I think that moving parts, moving either faster or more often than "normal", would wear faster. DARN my old Physics and Statics professors!!
