I don't disagree with your assertions, but it is a week between tiers regardless of how bad I've screwed the pooch on the release!Not a stupid question but a tough one.
Unlike some games that have a set time frame they like to stick to this ones more flexible.
Seems to me that how long it takes depends on other things I'm not sure OBD would agree with this next part.
How long it takes depends on how quickly the the higher tiers help OBD proofread his Update.
Which can depend on how good a day OBD had when writing it.
Also how quickly OBD manages to make the changes needed.
How satified he is with the changes.
And lastly how a good mood he in after all that.
So I guess in answere to your question I dunno just how long is a piece of string..
It released on the 7th, so it will go to the next tier today. I'm refreshing the Mega and Pixeldrain links with the latest Hotfix applied right now. (Big thanks to HP!
