This was discussed more than once in these forums. Unfortunately for your opinion, it has proven over time to be a good business model. People love that they can complete a tournament in less time than some other US facing sites take for their entire late reg. LOL
Personally I don't mind the no late reg on their regular tourney schedule. I wouldn't be opposed to a limited LR not to exceed 1 hour. If I want to play tournaments that run for 15 hours with a third of that being in late reg, there's a site for that. And I play there, but rarely for tournaments. Usually for games like Omaha/8 or Stud cash games, which of course aren't available on Global so meh.
At any rate, you can take solace in the fact that the MTT series they run, and select events on the regular schedule, have some late reg.
Some ideas to help you work with this while playing on your phone:
-Pick SNGS that are turbos, HU games, or jackpots... i.e. fast games for your X minutes of time killing.
-Play a cash game for X min.
-Register the tourney before it starts like you should be anyway... if you simply can't manage 2 tables on your phone, and simply can't chose a time killing format that won't overlap, then when the tourney table opens, just ignore it. Finish your SNG, then play the tourney. You may miss a blind or two, but that's insignificant on level 1.
As for registering causing you to miss a hand on your current table... well come on. You can miss a couple hands (and are rarely missing any tangible info on opponents for those 1-5 hands). I'm sure you're exaggerating when you say you "always miss them" because while you're logged in and playing you can't manage to register before the start. But the model is not likely to change since it works (they blow the gtds out of the water every tourney series, and generally the regular schedule always beats the gtds as well).
Good Luck in the upcoming Eagle series, 1 hour late reg FTW!
