What does it cost to level Jewelcrafting right now?

5.5kg in reagents at today's TW auction prices, over about 112 crafts. Sell the results and it comes back to 5.5kg.

Where do these numbers come from?

The skill thresholds are read from the game client data for build 12.1.0.68914. The prices are the region-wide auction house, refreshed every few minutes; these are the snapshot taken at 17:54 UTC.

Why does the route change when I reload?

Because the prices did. The cheapest recipe for a stretch of skill is whichever one's reagents are cheapest at that moment, and that moves through the day.
