How exactly do Hustle, Pressure, and Vital Spirit work outside of battle?

If anybody doesn’t understand what I’m trying to ask, comment and I’ll try to explain better.

As an impromptu test, I ran around the grass in Poni Gauntlet long enough to encounter 100 wild battles, half with a Pressure lead and half without (all battles were immediately ended by running away on turn 1, so calls for help were never involved). All the Pokemon that can appear in this grass patch have a possible level spread of 56-59, as is normal for every grass patch in the last two generations; it’s not like some older games where certain Pokemon in an area can peak out at a higher level than others (a phenomenon that gives rise to the so-called “Repel trick” in those old games).

The observed results of this test were that with Pressure, level 56/57/58/59 were encountered 6/7/5/32 times respectively. With a different ability that doesn’t purport to change encounter rates (Flash Fire, in case you cared), the distribution of levels was 15/11/12/12. This is pretty clear evidence of Pressure tampering with the levels, by having a fixed chance (50% would be consistent with this data, at least) of rejecting the randomly rolled level and replacing it with the top end of the range for that particular grass patch.

Usually, it’s the highest possible level for each species, each area, each encounter method, each time (when applicable), and each version. Sometimes, Pokemon of the same species but different levels will be registered separately. For example, let’s imagine that, when you use a super rod at Petalburg City without using an ability, there’s a 98% chance of encountering a level 20-35 Corphish and 2% chance of encountering a level 20-45 Corphish. When pressure, hustle, or vital spirit takes effect, the chance of a level 35 Corphish gets increased by 50% relative to the 98% or 49% relative to the entire sample space. Likewise, the chance of a level 45 Corphish gets increased by 50% relative to the 2% or 1% relative to the entire sample space. This results in a 49% chance of a level 35 Corphish, a 1% chance of a level 45 Corphish, and a 50% chance that the level is determined as normal (from my trying to get a level 45 Corphish, this seems about right).source
