:::::Ok LahaiRoi, I've taken a look at your spreadsheet and I see where it went wrong. I think I didn't explain well what my formulas were. I'm attaching a screenshot below of some of my calculations.
 +
 +
:::::[[Media:Fertilizer_Crop_Quality_Chances_Screenshot.png]]
 +
 +
:::::I'm also attaching my spreadsheet. If you wish to see the formulas they are hidden within the headers.
 +
 +
:::::docs.google.com/spreadsheets/d/1IwVMmuggkY2kzK6wrdUCWNndWI9r79YD3hDnvXIzbf8/edit?usp=sharing
 +
 +
:::::If you look at the screenshot first, you can see that our calculations differ first at Basic Fertilizer and Farming Level 10. Our gold chances are the same. For silver, you calculate 48.4%; I have 44.3%. If you look at the way I've calculated it, I've broken down the calculation into two: first the Silver Chance Formula and then the actual Silver Chance. My Silver Chance Formula is exactly as given by the code. At Farming Level 10 with Basic Fertilizer, that is the first time that 0.75 becomes the minimum, which you can see in my calculation. Our values differ because I use that first then apply the probabilities. Looking at your calculation at the same levels (Row 29), you have min(G29*2*(1-G29),0.75) as your innermost min formula. You're multiplying the probability to the silver formula '''before''' taking the minimum. The code given above is first calculating the silver chance, then checking for iridium quality, then checking gold, finally silver. So I think your formula needs to be min(min(G29*2,0.75),1-G29) in order to follow the code.
 +
 +
:::::Additionally, if I change my calculations to ignore the 75% cap to silver chance, my values match yours.
 +
 +
:::::If that doesn't make sense to you, add a few intermediate columns that calculate the chance in parts. Make a column that calculates the silver chance, then another column that includes the silver chance and the probability the code checks for silver quality.
 +
 +
:::::I'm confident that what I have is correct, please view my spreadsheet for the full calculations. If you compare mine to the current tables, all my percentages match, except for the Deluxe Fertilizer table, which cannot possibly be correct since it lists a nonzero chance of harvesting a regular quality. If everyone here agrees, I will edit the table.--[[User:APost-It|APost-It]] ([[User talk:APost-It|talk]]) 20:55, 10 September 2021 (UTC)

::::::Alright I see. I changed my spreadsheet and it matches yours exactly. So ya I had it wrong.

== XP per Day ==
 +
 +
Based on Margotbean's suggestion to move XP per Day here rather than including it in crops table in crops page. [[User:Xyrsis|Xyrsis]] ([[User talk:Xyrsis|talk]]) 22:58, 1 October 2023 (UTC)
 +
 +
Hello margotbean, I think XP per day is important as it is useful for determining the most efficient crops to level up your farming or foraging skills.
 +
There is slight difference to the most profitable crops as XP per day does not consider the price of seeds.
 +
I am going to use your spreadsheets to calculate the XP per day, edit on all crops table is on the way. [[User:Xyrsis|Xyrsis]] ([[User talk:Xyrsis|talk]]) 09:09, 1 October 2023 (UTC)
 +
This is the spreadsheet I used, [https://docs.google.com/spreadsheets/d/15zNaPQp-6GwIzm2ucuIkphNpSdECw3cI/edit?usp=sharing&ouid=114495551717477095381&rtpof=true&sd=true spreadsheet].
 +
 +
Table added with values from last updated spreadsheet, there are few missing crops' value. To avoid controversy regarding maximum harvest and growing days, I will calculate it based on Crops page Gold per Day value then calculate XP per Day value for it. [[User:Xyrsis|Xyrsis]] ([[User talk:Xyrsis|talk]]) 23:45, 1 October 2023 (UTC)
 +
 +
Missing xp/d values updated. Please check. [[User:Xyrsis|Xyrsis]] ([[User talk:Xyrsis|talk]]) 00:35, 2 October 2023 (UTC)
 +
 +
:So, this is the start of a discussion about the value of XP per day. Let's leave the discussion open ''before'' making the edits, please!
 +
 +
:Below is a mockup of the proposed section:
 +
<blockquote>
 +
<div style="font-size: larger; font-weight: bold;">XP per Day</div>
 +
Due to seed price, there is a slight calculation differences between the most profitable crops (Gold per day) and most XP yielding crops (XP per day). High quality crops grant the same amount of XP as normal-quality crops.
 +
 +
The general formula is:
 +
<code>Minimum XP per Day = (Max Harvests &times; XP per Harvest) / Growing Days </code>
 +
 +
'''Growing Days''' = <code>Days to Maturity + ((Max Harvests &minus; 1) &times; Days to Regrow)</code>
 +
 +
'''Days to Maturity''' and '''Days to Regrow''' are listed in each table.
 +
 +
'''Max Harvests''' is normally 1, but for crops that continue to produce, it is the actual number of harvests that can be obtained in the growing season(s).

==Notation==
 +
The formula <samp>XP=||16 × ln(0.018 × PRICE + 1)||</samp> means round everything between the double-pipes to the nearest integer. I've seen ⌊x⌉ and [x] being used for "round to nearest integer" as well. Does anyone have any thoughts about what notation should be used on the wiki? Perhaps providing an explanation instead of relying on symbols would be better? (although this would require changing wording in all 12 languages)... Thoughts? [[User:Margotbean|margotbean]] ([[User talk:Margotbean|talk]]) 21:11, 18 October 2023 (UTC)
 +
 +
:I agree with you on the opinion of giving the explanation of the symbol. It is confusing because <samp>||x||</samp> is not a well-known symbol for the function "round x to the nearest integer". It is only the number theorists who use the double-pipes to express the same meaning, while this notation is usually used to denote norms in mathematics. When it comes to a better expression, I suggest <samp> floor(x + 0.5) </samp> to make it more readable for programmers.
 +
 +
: BTW, I'm wondering if the exp of [[Qi Fruit]] is 0 according to the formula? [[User:群星之尘|群星之尘]] ([[User talk:群星之尘|talk]]) 08:03, 6 May 2024 (UTC)
