Another update by Eric de Groot with some graphics showing the bottom is in. He is also confirming what I expected/hoped to hear and that is that silver will lead gold even if silver isn't as ready for a surge as gold:

"Today I would add, when gold is ready, silver will likely lead precious metals complex whether or not its weak to strong hand transfer has been completed; a DI reading above 60% would indicate a statistically significant transfer in silver"
