How about hybrids that use some visual ballistic elements - still not VB and not DS
So something between.
Then you can measuring ball/rotor with pattern recognition without device.
For example wheel mapping - you say in topic that from person you get method that he thinks its good.
Is that opinion or based upon real play?
In theory hybrid also can be done using metronome as you explain in this topic if we add more visual ballistic elements into the calculation. Can be something between E2 and DS Hybrid.
Reason i reply is that you some time mention some one travelling using your computer and making large sum of money where others battle to win some money - all boils down to knowledge.
And quote Snowman means nothing - because hes opinion is based upon that edge is to small playing DS and thinks is not worth it and better to play VB - but there is a way between both and maybe can be solution for many
