How do the credits work for programming?

Programming requires a certain amount of credits per use, but you earn 10% back each time (amounting to 1 free use after 10 uses). You can get credits by swapping points on the Lonsdor App/device or by buying them from a local distributor. The $45 activation includes 160 credits.
