What are all the factors which affect escape chance?

Question

According to the question "What are all the factors which affect catch chance?" I would like to know what influences a Pokémon to escape.

Example: I do not know if this is a subjective cognition, but I think that Abra has a much higher escape rate than other Pokémon (the same like in the Pokemon Series).

Proof:

• Seen: 13 Times
• Caught: Only 7 Times ( where 3 are from eggs)

So the bilance would be 10-4 without eggs, what would be a catch rate of less than 50% (no statistical significance of course).

What are other factors except the Pokémon itself?

Answer 1

Like lois6b pointed out the chance to run off is determined by the Pokémon species. The chance to actually capture it is different, though.

---

If you hit it with a ball you have a specified chance to capture it:
BaseCaptureRate: 0.4 (*) - modified by these

This will determine the chance to actually capture it.

---

If it gets out you get another dice roll:
BaseFleeRate: 0.99 (*) - modified by level (based on experience)

This determines the chance of the Pokémon to run away. So Abra has a 1% chance to stay.

The only exception is a soft ban: This will override the BaseCaptureRatewith 0 and the BaseFleeRate with 1. So every Pokémon runs off with no chance to capture it.

(*) = Based on Abra

Answer 2

As you can see here: https://gist.github.com/anonymous/077d6dea82d58b8febde54ae9729b1bf#file-game_master_v0_1-protobuf-L8600 there is a variable in the pokemon that indicates that.

TemplateId: "V0001_POKEMON_BULBASAUR"  
  Pokemon {  
    UniqueId: V0001_POKEMON_BULBASAUR  
    }
    Encounter {
      BaseCaptureRate: 0.16  
      BaseFleeRate: 0.1  
      JumpTimeS: 1.15  
      AttackTimerS: 29  
    }

Answer 3

Great question! I've been thinking a lot about the probabilities involved in catching Pokemon. I have observed that "curveballs" and balls thrown with any kind of spin have a higher catch rate. Throwing like this is harder but if you can catch the pokemon, it is much more likely to stay than just lobbing the ball at them. I don't have any numbers backing this up but it would be great if someone does.
