function recoup(aetherPerWax, stakeValue, itemCostInWax) {
  var aetherPerDay = (24 * stakeValue);
  var daysUntilOneWax = (aetherPerWax / aetherPerDay)

//usage: recoup(5200,40,20)
// excchange rate is 5200 aether per wax, the item gets 40 aether per cycle on rPlanet and the item cost 20 wax.
// It'll take ~108 days to recoup what I spent
