Calculations[edit source]

I am under the impression that this page, as well as the other "Making ... potions with scroll of cleansing" pages, contain incorrect calculations. The pages state that the 10% bonus causes the 9 herbs to turn into 10 unf potions on average. However, to my knowledge, a 10% chance of keeping your herb should result in 10 herbs turning into 11 unf potions on average; 9 herbs would turn into 9.9 unf potions. As the calculators are used for large numbers, this rounding can cause inaccuracies in the long run. 3600 Herbs * 1.1 = 3960, which'd leave you with 40 vials spare, and 40 unf pots worth of profit less. If the calculations should be based off of 4000 vials of water, to be correct, one should need 3636 herbs on average.
Other than that, some outdated-ness nitpicking: you'd get at least 4000 Herblore experience for making 4000 unf potions now. 134.58.179.35 09:25, May 10, 2013 (UTC)

Hey, thanks for the message. These guides are indeed outdated -- coincidentally we were talking in the last few minutes about finally getting the project done. As for the math of saving herbs, I think my numbers are correct and here's why: the savings from the herb are compounded. So say you start with 1000 herbs. You make 1000 potions, keeping 10% of the herbs (100). With those remaining 100, you do the same thing, creating 100 potions and saving 10 herbs again. You do the same thing again, making 10 potions and keeping one herb. You'll end up making 1111(.111...) potions from 1000 herbs, which is equivalent to saying you'll make 1000 potions out of 900 herbs, or 4000 potions out of 3600. Instead of thinking of it as saving 10% of your herbs, think of each potion as costing 0.9 herbs. Hope that helps. ʞooɔ 09:44, May 10, 2013 (UTC)
Aah, I see where you're coming from. That does indeed make the math hold ground; seems like I overlooked this. Sorry and thanks ^^ . 134.58.179.35 11:19, May 10, 2013 (UTC)
Think of it as 11% instead of 10. i have updated the methode, as it didnt count in banking time. the 12 seconds is for making the potions, but when the banking time comes in, its around 23 seconds per round. that reduced the armont from 4000 to 2000 potions on average. 134.58.179.35 22.02, June 17, 2013 (UTC+1) 87.72.3.48 20:03, June 17, 2013 (UTC)
It's not that it didn't count banking time, it's that the speed of making unfinished potions changed between when it was written and now. 23 seconds seems to be a good time, so I'll call it 2200 potions per hour. I don't agree with your change about the scroll of cleansing though. ʞooɔ 20:17, June 17, 2013 (UTC)
I agree with the first guy actually, the scroll of cleansing although advertised at 1/10 chance of saving herbs, is actually more like 11.111% or essentially 1/9. This would make the profit per unf potion 1,907.56 coins rather than 1,817.1 coins, a difference of 4.98%. This would make the hourly profit 4,196,622.22 coins. Additionally one inventory I measured to be an average of about 25 seconds including banking time which would mean that one would make about 2016 potions per hour. Using both of these corrections that brings the hourly profit to about 3,845,632 coins, which explains why the 1/9 versus 1/10 deal doesn't seem to affect it much when you go and test it.
