Specifically, this stated EPA depends on the probability of rare success getting the [[Bottle of Fourth City Airag: Year of the Tortoise|Airag]]. Then we can calculate the expectation, so let's do the math!

Firstly, we assume that the probability of the normal failure and alternative failure are equal (25% each, for an overall failure rate of 50%), and also thusly that the game's stated overall failure/success probability of 50% is in fact true. We will also assume no value for Expertise of the 2nd/4th city ([[User:Druut|the writer]] pulls the old "leaving that as an exercise to the reader" trick), but they do have some value in the lab. Now, since the chance of a success becoming a rare success is 3%, we know the true probability of a rare success is half of that, or 1.5%, which makes the probability of a normal success 50% - 1.5% or 48.5%.

Now, since we don't know the true rate of rare success, we assign it the variable <math>x</math>, representing the percent chance of rare success (overall—NOT the probability that a given success will be rare [though that should in this case just be <math>2x</math>]), which makes the probability of a normal success (0.5 - <math>x</math>).
  
 
Now, we consider the values of each outcome by their sell values:

This gives us an expectation <math>EPA_{reach2}= (0.25)(0.45 E) + (0.25)(0.95 E) + (0.485)(5E) + (0.015)(62.5E)</math>

−
This gives an estimated EPA of 3.7125{{E}}.
+
If only there was a way to visualize how our EPA changed with different values of <math>x</math> numbers... Oh right, graphing! From [https://www.wolframalpha.com/input?i=plot+%280.5%29%280.53%29+%2B+%28x*62.5%29+%2B+%28.50-x%29%285%29+for+x%3D%5B0..0.05%5D this plot] we can see the following results:
 +
 
 +
*Without any Airag at all, this generates an expected 2.765 EPA
 +
*This hits 3 EPA at ~0.4% rare success rate.
 +
* At 1% rare success, we get 3.34 EPA.  At 2%, 3.915 EPA.  3%, 4.49 EPA! (These higher probabilities are likely not the case, however—more data is needed.)
  
 
It's important to note that it does cost an action to enter as well as 100/50 drops of honey, so when calculating your final EPA, you'll need to multiply by a factor of <math display="inline">\frac{N}{N+1}</math> where <math>N</math> is your actions spent reaching, then subtract your personal honey cost. You also don't have access to any cards, which can be significant depending on your goals and playstyle.

Ultimately, we really need a large sample size to determine the small mystery probability and until that data is collected, it's hard to say just how profitable this should be. It's important to remember that even with an expectation of some EPA, it is just that—an expectation: while one <i>can</i> expect to approach that number if you try enough times, it can take a very long (technically infinitely long) to reach it. This is ultimately still an RNG grind, and some will be luckier than others. So while this analysis was prompted by my annoyance at the vagueness of the stated "3+" expected EPA, I now believe that it's possibly in fact the best way to succinctly present the results. Go figure.
 +
 +
Still, this has the potential to be a very simple, very profitable grind especially for those like [[User:Druut|me]] who have very middling stats (low 100s), unlocked parabola quickly before anything else, and are basically flat broke.

Using up Exhaustion is hard in the mid-game, but also profitable. Exhaustion in itself is around 200 {{e}} per week. If you have {{IL|A Custom-Engraved Skull}} from {{FontRose}}, you should use those most weeks, leading to a net gain of 160 {{e}} for 2 skulls. The exception to the rule is when the Phantasist is around - then you may be able to spend all your exhaustion through other means.
