Tale 11 · Measure a tank once, then get the cheapest treatment for any board you need. Everything runs in your browser — nothing leaves this page.
How fast each attribute moves on the selected tank. They belong to one tank and nobody else’s are any use, so a new tank starts empty.
Untick anything you haven’t got. Weight is what a deben of it costs you: the search minimises total weight, so put Oil high and Water low if that is how your stores look. Leave them all at 1 for the fewest debens.
Every board type you need and how many. A board with spare properties is accepted wherever a subset is asked for, so hard glossy rotproof covers an order for hard rotproof — but making the plainer boards on their own may work out cheaper. This works out which grouping costs least once tank loads are rounded up to 500.
