"Speed lock far too aggressive?"

#PokemonGO: Is anyone else experiencing Sightings going blank for periods and 'Try again later' messages when spinning stops while walking?As far as I know this is what happens when the game deems you to be moving too fast, with the latter being a form of Speed Lock until it thinks you are no longer travelling too fast.This has happened to me on a Sony Z5C and OnePlus 3 so not older phones, and both have decent GPS with no drift visible.I get the feeling the game is smoothing out GPS reading when displaying the avatar in game, but when it takes readings internally sometimes they are just far enough apart to indicate speed above 25MPH and, rather than taking an average of three or more readings its immediately triggering the 'too fast' activities, although I do not get the 'I'm a Passenger' popup via /r/TheSilphRoad http://ift.tt/2g8SuiY
