Meanwhile enough people have subscribed the Z systems for us to see which systems are significantly preferred. Strangely, 95% of all users subscribed Z12. Only a few subscribed Z3 and only two so far subscribed Z5.
This is about the opposite of what we expected. We've put most of our own money on Z5, as it comes the closest of all to a regular income. Also the Z5 drawdown is limited, while drawdown of the other systems is theoretically unlimited. If you think about which system to subscribe, have a look at Z5.
