The He3labs Radix Economic Calculator appears to have an error in how it’s calculating the New.XRD.Received column (and therefore the XRD.Balance column too). The amount it’s showing for the New XRD Received is too high.

Let’s take an example using the default parameters. In week 2, you start with 1000 XRD (purchased in week 1). The total XRD at the start of week 2 is 112,259,584. And the Expansion.XRD is 23,333,333. 10% of the Expansion.XRD goes into the Radix Team Incentives, which leaves 21,000,000 to split among the XRD owners.

New.XRD = Your.XRD / Total.XRD * Expansion.XRD

New.XRD = 1000 / 112,259,584 * 21,000,000 = 187

So the amount of New XRD received at the end of week 2 should be 187. But instead, the He3labs Investor Table shows 380.

Perhaps I’m not understanding the calculation correctly. If not, could someone point out how the New.XRD is supposed to be calculated?
