Try not to flame good old boof too badly,at least he makes an effort (unlike someone else whos beyond reason).
K-Ar dating is only accurate on rocks between 100,000 - 4.3 billion years at a resolution of 1 million years. Other methods are used for less than this (carbon 14 dating - accurate before 50,000 years - but that only works on once living material, and other isotope's with smaller half lifes).
If you see a half-life decay curve you'll notice that its really steep to start with and really flat at the end. That's why they make limits for the range between start and end because result's at these points are not accurate.
Its to do with the decay rate's and sensitivity of equipment, even after 100,000 years only 0.005% of the potassium would of decayed into argon.
So to apply such techniques to something 20 - 25 years old is ridiculous (makes you wonder why they didn't give them the expected age). Kind of like asking you to time an event that lasts 1/10000 of a second.
Also the sample cannot be used if they've reheated and recrystalised (a trained geologist would be useful here).
And if those tests had been done properly they would of done them at mulitiple lab's with multiple samples.
