TheLastFinale

Hello. IGN: Final Tease.
I managed to get the "Suity Level Maximum" within the 2nd day of release, with an augmented Imcando Pickaxe, Overload, Lava Titan, and Magic Golem outfit, while mining phasmatite. Now, I'm not here to brag. Over the past few days I have heard countless people ask, in-game, for advice on how to get this achievement. This has caused me to launch into a full-scale investigation of what the minimum requirements should be (RNG-based, of course) to get that fancy RuneScore.

My steps have followed like this:

  1. read the Mining page on the Runescape wiki at least 17 times over.
  2. Try and determine a base damage from my mining and strength skills
  3. isolate the amount of damage "rolled" each time per XP granted. (by isolate I mean figure out the damage I'm rolling independently of my Mining and Strength skills)
  4. average out my damage based on 3,000 non-critical, non-boosted strikes between 1-99% stamina
  5. try and determine a "damage-roll-average"
  6. repeat steps 3-6 on critical strikes
  7. compare the average normal-damage to the average critical hit damage to determine a rough estimate for Critical Hit damage modifiers
  8. finally, implement all of this information into a calculator to put into a strategy guide or something on the runescape wiki so people can determine the minimum requirements for this achievement and also the likelihood they'll get it at those mininimum requirements or better.

So, in theory, this has been working out great.

I have run into an inconsistency though, and would love some advice from some other tryhard rando looking to waste some time on math.

The inconsistency

I'm having a problem in calculating damage out. I'm back at phasmatite, practicing the whole time.

Mining = 95 +95 Damage

Strength = 88 +8 damage

I'm using the Pickaxe of Earth and Song. +40- 140 damage

With all of these combined, my minimum damage with any given pickaxe should be 103, and my minimum damage should be 143 with the Runescape P E S dispenser.

I do not have any other boosts active, no titan, no aura, no overload, nothing. Just a Grace/Luck combo to keep it interesting
Based on the information present here and here, My damage and exp equations should look like this

EXP = Damage * Rock Modifier * 0.4

Damage = EXP / Rock Modifier / 0.4

Phasmatite's Rock modifier is 0.8, NetHardness is 0 due to greater hardness than rock providing no extra damage

therefore:

EXP = Damage * 0.8 * 0.4

Damage = Exp / 0.32

Here's where the issue is, and where I'd like some community help, if anyone's interested.
Sometimes, I can get an EXP drop as low as 39.
If we plug this in, then our damage done is

Damage = 39/0.32

Damage = 121.875

Given the current calculations in the wiki, my minimum hit with a PES dispenser and my current mining/strength stats should be 143, making the least amount of EXP I get in a single swing should be 46.

There's only two things I can come up with that may be affecting my maths (which I've quintuple checked, with other people now as well, too).

  1. Stamina is not a damage multiplier in the way that increases damage at full Stamina, but rather decreases Damage done when below 100% Stamina. I include this idea because I've been working strictly within the range of 1-99% stamina. I admit, I can only achieve a 39 XP drop at 0% stamina, but I can get as low as 41 in middle-range stamina, which is still 5 less than what my minimum should be.
  2. the formulae for calculating out Damage and Experience is not entirely accurate, and there's some missing step or calculation we're not seeing.
  3. The damage is rolled at a different time than what the wiki portrays, or the experience drop is affected/unaffected by mining/strength stats in ways unclear to me.

If anyone knows how to page a Jmod, and see if they'd shine some insight on this, I'd be more than happy to continue with my studies and figure out how to get you, my friendly neighborhood Runescape Adventurer, closer to getting that Suity Level Maximum runescore. ;)

My ultimate goal is to figure out average damage-rolls that aren't affected by levels with the PES dispenser, find out average critical strike damage-rolls and then compare the two to determine a rough estimate for how much a critical strike modifies a player's hit. This is more or less the missing piece I need to find out exactly what the mininimum requirement is to obtain the achievement, because the rest is just math. :) Thanks for checking me out, this is my first post here, and I look forward to any and all help, criticism, "gg m8"s and "$11 btw"s!

Last minute edit: sorry for the organization of this post, my head's all over the place and I hope that this is more or less straightforward to read. I've been using Ruby to speed along my data processing, but once I started noticing (perceived) damage-rolls less than 40, I got curious.

Your theory about stamina being calculated as a penalty rather than a bonus is correct.
