132.5kg in reagents at today's TW auction prices, over about 105 crafts. Sell the results and it comes back to 132.5kg.

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 20:54 UTC.

Why does the route change when I reload?
