Pokemon-go – re-encounter a pokemon that ran away from me

Pokemon give no visual indication of being about to run away.

However, Pokemon such as Abra are (still) almost guaranteed to run following a failed capture attempt. The chance any given Pokemon will run away on the first throw (without any sort of modifier) is given in the BaseFleeRate variable from the decoded ProtoBuf file.

Additionally, Pokemon with orange or red rings have a higher initial chance of running away. All Pokemon will run after enough turns have progressed, as the chance of a run increases each unsuccessful turn.

I noticed this too. It could be a bug in the game that causes the GPS to be inaccurate with the paw prints. A Growlithe showed up near me, allowing me to capture it, but my grid says 3 paw prints for all the 9 Pokemon, even with the white pokeball loading symbol gone (done loading). Also, grass/leaf patches don't always mean there is a Pokemon. I ran far to a rustling patch before, but all the Pokemon on my grid were 3 paws away. More info on rustling leaves

Although I believe this is an unintentional bug by Niantic, I would recommend searching primarily for just 2 and 1 paw print Pokemon if it shows up. The 3 paw prints seem buggy, even though it means 150 meters to 200 meters within range according to this answer: Step Distance Try to go with a group a friends so that you cover more area and find Pokemon more easily. In addition, you can try going toward leaf patches for a slightly higher chance of an encounter.

EDIT: As of now, I have iPhone 6s with version 1.0.2 in the app store of Pokemon Go. The in-game version says 0.29.2
