This is not the kind of rarity math I was talking about.
Can you put it into an equation that does not use exponents?
Stuff like "'09-'17 : 4+1^t" is way too scary looking of an equation for me to be doing for calculating trades, and is the kind of extreme that would also put me off trading in the other direction.
If I can't do it in my head, then it's not viable for me. I'd literally much rather jerk in the total opposite direction and say "Yeah, OMGSRs are worth all other OMGSRs" than touch exponents in trade math with a ten-foot pole. My negative reaction to graphs and exponents is visceral.

Also, this is super far off from any type of valuation I'd have for 09 rares/vrs. I'd barely trade the ugliest 09 rat out there for a '10 rare and a '23 rare. If we're using a line graph, the line between older years should be steeper and become more gradual as we get into newer years.
Take a graph like this for example:

The
Green Line is the old 2:1 Method
The
Purple Line is the +2+1 Method with +1 beginning at 2019.
The
Aqua Line is a new method that starts with +2 from 2009 to 2012, does +1 for 2013 and 2014, then goes to +0.5 for 2015-2020, and 2020-2024 is +0.25.
I understand that that is literally exponential, but it's being put into a way where I can remember the rule and use addition to figure it out.
Doesn't have to be exactly like that, but I'd prefer if +2 went from 2009-2011 or 2012 at least and then I.. Don't have any personal investment in trading my 2009 pets for any pets after like 2012 (unless they're slumber party, fae, or space event pets). So my input after that point means less since I don't do those types of trades.
Here's what that looks like in a chart:

Where you lose me here, though, is that finding out what a 2015 Rare is worth with this graph is really difficult for me. Which is why with my +2+1 method, it just "resets" and starts at whatever year you were at.
Your 1 2009 rare? 12 2015 rares or 14 2016 rares etc
Your 1 2015 rare? 2 2016 rares, 4 2017 rares, 6 2018 rares, 7 2019 rares etc
(Math Ramble, look for the bolded 'math ramble over' to skip)
12:14 is not 1:2, I'm well aware of that. I'm also totally aware that literally none of the other math checks out. The 12:14 ratio between 2015 and 2016 is
just for calculating how many pets are valued for an 09 rare. Even though I have that 12:14 ratio, I still have no idea how many 2016 rares a 2015 pet would be worth, that's not what's being calculated in that trade.
I literally don't even know how to google it to look up that math for it to be 1 to something. All I can get is like.. 6:7?
This entire process gave me a massive headache to run though, and I don't even know if any of it is right despite running it through calculators so many times. I'm
so confused.
And then it's stuck there so 6 2015 rares are worth 7 2016 rares? But then that means that like, each side divided by 6 would be 1 2015 Rare for 1.16 2016 Rare which..
How do you even value that? I don't like decimals. They hurt my brain.
1.16 ? What even is 0.16 of a 2016 rare? I guess that means its 16/100, 8/50, 4/25, 2/12.5, 1/6.25.. Comparing that to 2:1 rarity tag math of 1 r = 2 EUC = 4 VUC = 8 UC = 16 C = 32 VC.. 1/8 is 0.125 so a 2015 rare would equal.. 1 2016 Rare and about a 2016 Uncommon? That's not quite right though, you're still missing 0.035 of a rare.
1/16 is 0.065
1/32 is 0.031
Where do you stop? 1 2016 Rare, a 2016 Uncommon and a 2016 Very Common?
Meaning you're still missing 0.004 of a rare, which makes it probably the "most fair" you can probably get.. Unless like..
32 VC = 64 EC = 128 OMGSC..
1/128 is 0.007. Which makes the total value of 1 2016 Rare, a 2016 Uncommon, 2016 Very Common and a 2016 OMGSC overpay for a 2015 rare by 0.003. Which is the fairest swap you're getting, because without the omgsc, the 2015 rare is overpaying by 0.004, which is more than 0.003.
I hate that. That's so complicated and precise and hard to calculate, nobody is realistically doing that. That's just for one pet as well... And that's using the +2+1 method, which, during all the math I was doing, I totally forgot I was using that method to get the 12:14 ratio.
(Math ramble over)That was ridiculous. I enjoyed raking my brain over hot math coals for a moment, but god that would be worse than a personal purgatory of stepping on infinite legos if I had to do anything like that for
every trade.
That being said, having done ALL of that math, I do think 1:1.16 is a decent trade for a 2015 to 2016 rare. So I don't actually think that ratio is far off.

Your 2015 rare is still worth 2 2016 rares with my version of +2+1, all the way up until 2019 where it is worth 7 and not 8 rares from 2019. I was
never doing exponentials or fractions until now, it'd just be way too complicated to figure any of that out with that kind of math.
That being said: I never planned on trading my rares through many years anyway, I did it like that for a reason. I wanted it to be stupid for you to trade me 7 of your 2019 rares for my 2015 rares, because
I do not want your 7 2019 rares for my 2015 rare. Nor do I want the opposite trade. I want to trade pets within similar years of each other, outside of super-high-value trades or when I'm overpaying, and that's it. I don't want any amount of your 2019 pets for my 2013 pet. I don't even want your 2016 pets for my 2013 pets unless you're offering me a space pet. I might want your 2015 pets for my 2013 pets, but you're pushing it at that point.
But no matter what kind of trades I actually want to do, it should be fair for people who want to do the type of trading that I'm not invested in right now, and it'll help me in the future when I do want to do those types of trades, too.
