A lot of attempts have been carried, but it has not been possible to get a reasonable leg balance and a good gain. In the following the best result is presented, so called variant “V4”.

In practice, there is no balance at all and the gain is hardly sufficient. This case has been retained for the next Y-Factor tests.
