Global plays like live tables, most likely due to the interface, and not being able to track hands. Play is so loose and soft that it increases variance quite a bit. Over the last 30 months, I've had about 8 losing months. 3 of which were all in a row (about $30k). Made it all back in 2.5 weeks when the run bad stopped. That's just how Global goes. Its like being able to multi table at a card room.
I wouldn't try anything close to GTO on Global either, btw.. everyone is too exploitable. Very specific population tendencies, vulnerable to an alert, exploitative player. The best way to lose money on Global is to try to multi-table a GTO style, at least for me. Stick to 4 or less tables, take notes and hunt the whales.
I sound like a shill, but Global has been good to me, even though sometimes I CANNOT WIN AN ALL IN TO SAVE MY LIFE
