1. What a route is actually for
Gathered material is feed for two stations: Smelters over the orange lava, and Forging Shrines in the broken white pods that fire a blue-green beacon. Each recorded Forging Shrine recipe cost 50 DNA on top of its two materials, so a route is only worth running if the station you are walking to accepts what you picked up.
2. Station output, not a points total
Turn in the objectives you can complete and smelt the results into Research Vials, DNA and Cores. Vial production comes from Smelters and Forging Shrines rather than from a points total you accumulate in the background.
3. Carry what the hotbar holds
The creature hotbar in recorded footage has three slots, which is why two short loops back to a station beat one full tour of the island. The recorded material table, with a timestamp for each pick-up, is on the Items, Materials & Recipes page.
