What processes do you think would speed up decay rates without leaving any other evidence at all? I mean, such an event ought to have left evidence outside of decay itself -- something powerful enough to suddenly push the worldwide quantities of potassium quickly into the argon column would presumably leave more evidence than just argon. Do we have die-offs correlated to spikes in daughter elements? Do we see differential decay rates at different levels of the lithosphere, which could be expected as a result of shielding from radioactive events?
Your hypothesis has implications which make predictions, two of which I've listed. What does observation tell us about those predictions?
