I'm in a ski share house in the northeast. Last winter I organized a ski tuning clinic put on by the local ski shop that does race tunes. I thought that only the expert nerdy skiers in the house would be interested, but everyone was fascinated. Most of the attendees won't tune their own skis, but they will know what to look for in their skis, and when to take them in. Also, in the north east, tuned skis absolutely matter, whatever level you are. My wife has been learning to ski and had trouble with ice. So I put on her beginner skis, and said, ahh no wonder, went back and tuned them. Then I put her on my slalom skis because she didn't trust her skis to initiate a turn (slalom skis are famously quick to initiate), and she could turn them quickly. Then I tuned one edge of each slalom ski with a more aggressive tune, but she could swap back to regular if she wanted. Finally, she was skidding her turns too much, so I put her on my GS skis, which forced her to patiently start the turn then follow it through. She now has a good idea of when she's having trouble with the ski shape, the conditions or the ski tune after 35 total days of skiing. If you put a beginner or intermediate on race skis, make sure the tune is mellow enough. Slalom skis at 0.5 and 86, will hunt when not turning, and can grab an edge throwing you to the ground. At the steeper angles (86/87 vs 88/89) it is much harder to skid the ski for speed control. When you head out with a beginner, you can always bring a diamond stone and detune the tip/tail, on the mountain even. They will notice the difference and appreciate it.
