Calculating Effective Ranges for (Most) Projectiles

Because I'm a nerd, I did some calcs to determine what the "effective range" of most projectiles are in the game.

Definition

To define a projectile "effective range", we need to look at what's important: direct hits or just splash?

In most cases, splash is only 1/2 or less of the total damage of a shot and even has a falloff gradient from impact (i.e. further away from impact point, less damage splash is). In these cases we care about direct hits. If there's no difference between splash damage vs direct, then we care about splash. Hence we need 2 formulae:

For direct:

Dodgeable_Direct_Range = (proj_size_radius / avg_hero_speed + avg_reaction_time) * proj_speed 

For simply just splash:

Dodgeable_Splash_Range = ((proj_size_radius + splash_radius) / avg_hero_speed + avg_reaction_time) * proj_speed 

i.e. the logic these formulae is: assuming the projectile is aimed perfectly directly at the target, at what range is it feasible for the target react + walk in a straight line to retroactively dodge a direct shot/splash of the project?

Because if a target can react + move to dodge a projectile no matter how well you aimed it, then evidently you're at a range where the projectile isn't being "effective". Or alternatively, if you're at a range where targets can reactively guarantee only receiving at most splash damage, then you're in a range where you're at most only achieving fall-off damage i.e. not in effective range.

Results

Before I show the table, these were the assumptions made:

• average human reaction time being 0.25s which is based on https://humanbenchmark.com/tests/reactiontime
• projectile size radii sourced from https://us.forums.blizzard.com/en/overwatch/t/projectil-hitbox-sizes-width-table/454600 (it used a custom game mode to derive the diameter of projectiles)
  • there are some projectiles that couldn't feasibly be derived from this and hence they've been excluded from the table (e.g. orisa primary or echo primary)
• average walk speed being 5.5m/s which is actually the case for most heroes. this and other data like splash radii is sourced from https://overwatch-archive.fandom.com/wiki/Overwatch_Wiki
• further note these numbers do not take into account projectile arcs.

So without further ado, here is the table.

*These abilities' dodeable splash range shouldn't be treated as the same as others due to delay in explosion/splash.
