Oh duh, yeah, sorry, was assuming that the output was the state. If the output is trimmed from the state, you can def have repeated outputs that still have unique state and thus different successors.

And, due the way LCGs work, once you *do* repeat a value, you loop the sequence. Anything not hit before the first repeat will never be hit.

The Android browser was just Chrome, occasionally forked and then fiddled with, so that by the time it was released in a new Android version it was several versions behind real Chrome, and thus was always missing whatever latest features had been added.
