How much is left when the progress bar says 150

You started with 40 SC on a 10x requirement, playing a game that contributes 50%. Your account shows 150 SC of credited progress. How much more must you stake?

Working

  1. The requirement is 40 x 10 = 400 SC of credited wagering.
  2. At 50% contribution, two coins must be staked for one to be credited, so satisfying the whole requirement means staking 800 SC.
  3. You have 150 SC credited, leaving 400 - 150 = 250 SC of credit still to earn.
  4. Earning that 250 SC of credit means staking 250 / 0.5 = 500 SC.
  5. The figure that matters is the one the progress bar does not show. It reads 150 of 400 and looks 37.5% done, but if all prior play was at the stated 50% contribution you have staked 300 SC of an eventual 800 SC — the same 37.5%, expressed in a unit that makes the remaining work visible.

Takeaway

A progress bar counts credited wagering. Your balance is spent in staked wagering. When contribution is below 100% those are different numbers, and only one of them is the work left to do.

Limitations

This is a theoretical calculation, not a prediction. It describes an average over a very large number of repetitions and says nothing about what will happen in any particular session.
