Basically the people at Giga thought:
Ok we can't just play the well balanced Elite scheme, we need to introduce something new even though it's a 1:1 copy of the same scheme because we can't admit that there already schemes that are good enough to be effective as a competitive scheme such as elite so we need to add moles and do minor things and then we can call it Giga scheme.
I always had to do an inner facepalm when I thought of Giga scheme because it was so ridiculous copied from elite.
Ah yeah, hi Sören. =)
