Raw data from heavy metal pollution testing, with discussion of possible conclusions. Feel free to discuss or to post your own raw data. -Orashin
Mine location: -1550, 7587
Enhanced mining level: 8x
Raw data
- Pull 72: Mine drops to 96% purity
- Hypothesis: Next drop will happen at pull 108
- Pull 90: Jump from 0% to 100% heavy metals pollution
- Time: 12:32 AM MST on 1/21
- Range: 94 coordinates
- Hypothesis: Further mining increases range of pollution
- Due to the fact that I don't want to run 94 coordinates after every pull, checking range after every 10 pulls
- Pull 108: Mine drops to 91% purity
- Hypothesis holds. Therefore, mine will drop to 0% purity at 360 pulls if multiplier stays constant.
- Pull 180: Quit for now. No change in range.
- Time of pull: Shemu IV-20, 1:08 PM (2:20 AM MST 1-21)
- Will check pollution rates later on to see how it subsides.
- Shemu IV-21, 5:47 PM (12:31 PM MST 1-21): No change in range or percentage.
- Shemu IV-22, 2:08 PM (7:51 PM MST 1-21): No change
- Shemu IV-24, 10:27 PM (3:38 PM MST 1-22): Still nothing
- Shemu IV-26, 1:50 AM (1:42 AM MST 1-23): Nada
- This is begining to look fairly strange. Given conventional wisdom, some pollution should've cleared up by now. I'll give it a few more real-time days, then begin trying other things.
- Shemu IV-28 4:59 AM (7:52 PM MST 1-23): Nothing
- Akhet I-1 11:46 AM (11:49 PM MST 1-24): Down to 87%, same range.
- Guessing we won't see any change in range.
- Estimated range in time it took to clear up: 3-4 days (real time). Probably closer to 3 Teppydays.
- Next bit of business: Get a few data points for pollution clearing. If it clears up in linear time, I can use this to determine exactly when it started clearing up pretty easily. If not...well, still may be able to, but who knows.
- Akhet I-3, 7:33 PM (7:37 PM MST 1-25): 57%
- Rough calculation: About 10% recovery every 6 Teppyhours. Which doesn't account for the 3%, but maybe it's about (10/3)% every 2 Teppyhours. Next data point should help clarify.
- Akhet I-5, 7:00 PM (12:25 PM MST 1-26): 37%
- Akhet I-9 2:07 PM (8:54 PM MST 1-27): 7%
- Now it may be...who knows? I gotta actually, y'know, plug these things into a graph.
- Question: Where did the 7% come from? Retested with 1000 tadpoles (been using 100) and it says 7.7%. At 10,000 tadpoles, 7.70%. Seems to be dropping in 10% decrements, so aren't we seeing measurements like 90%, 50%, 10%, etc.?
Other hypotheses:
- Pollution clears over time.
- Almost certain, as this one is based on anecdotal evidence. Still needs confirmation though.
- Pollution is related to mine purity level.
- Growing vegetables nearby clears up pollution.
- Pollution does not appear immediately after mining, but a little while afterwards.
- Doubtful at this point. May be worth it to build a new mine and do 60 pulls on it, then checking for pollution later.
- Pollution only occours in tandem with smelting.
- Rate of pollution depends on enhanced mining level.
- Pollution range depends on enhanced mining level.
Conclusions:
- Heavy metal pollution is caused by enhanced mining. No doubt about that.
- Pollution appears all at once. It goes from 0 to 100 over the course of a single pull once the threshold has been met.
- Pollution does not appear to spread any further. Not a certainty, but if it does, it would've likely spread over the course of the second 90 pulls, after the pollution appeared.
- As for practical applications, they are fairly unknown at this time, at least until results for how long it takes pollution to clear over time (if that is the case). Best suggestion: Track number of pulls, make sure it does not go above 90.
- Possible experiment: Start at 45 pulls, wait one pollution clearing cycle, do another 45 pulls.
- Possible experiment: Get normal miner to do some pulls, check and see if that has any bearing on how long it takes to cause pollution.
More to follow as more results come in.
