It is normal, but you should use the parameters with care. The maximum margin is neither 4984 nor 4064, but more like 15000.

The reason is the capital reinvesting, which does not allow anymore to determine an initial capital from margin and drawdown. For doing it nevertheless, Z9 simply reduces the maximum drawdown and margin by the ratio of start and end capital. So the values are not precise, but estimated. In most cases they are ok, but with your asset list apparently quite off. So be careful. I'll put a warning in the manual.
