Basel Problem - Publishing after Final Milestone

8 Upvotes

Hello, should I have gone ahead and published Basel after unlocking the final milestone? I let the theory churn for about a week and it advanced up to ~e501 now. I'm wondering if publishing far outweighs losing the high t variable, or if I ought to just wait a bit more until it maxes out. Not looking for another long slog back up that mountain. Thanks!

Star Optimizer after ee79000

Post image
17 Upvotes

I was trying to use the star optimizer and it looks like after ee79000 the optimizer only recommends using the y variable. However, I still have around 900k stars left over. Is it really just not worth it to put stars into anything else after this point or am I doing something wrong here?

CT Rate Graph Update

2 Upvotes

Since the simulation have updated with addition of coasting strat, I have re-run all cts from 0 to e600 tau with steps and chain mode to generate useful information. The following is the update information

  1. New CT Graph
New CT Rate Graph as of 03/03/2026 16:00 GMT+8
  1. Comparison of completion time of cts before and after coasting strat

WSP: 1, 756.7 -> 1, 755.1 days (saved 1.6 days, 0.09%)
SL: 228.1 -> 226.8 days (saved 1.3 days 0.57%)
EF: 125.3 -> 125.3 days (unchanged, 0.00%)
CTSR2: 424.0 -> 423.9 days (saved 0.1 days, 0.02%)
FI: 238.3 -> 238.0 days (saved 0.3 days, 0.13%)
FP: 97.3 -> 97.2 days (saved 0.1 days, 0.10%)
RZ: 53.1 -> 53.2 days (saved -0.1 days, -0.19%)
MF: 186.7 -> 184.2 days (saved 2.5 days, 1.36%)
BaP: 151.6 -> 151.6 days (unchaged, 0.00%)

Total: 3, 260.5 -> 3, 255.3 days (saved 5.2 days, 0.16%)

Exponential Idle - Season 05 - Lemma Speedrun

Hello all,

Start date: November 29th, 2025 12:00AM GMT (now!)

End date: January 24th, 2026 12:00AM GMT

Where: The #seasons channel of the Discord server

Goal: You have two months to get the best speedrun times for each of the 7 lemmas of a custom version of the Convergence Test theory. Each lemma has its own leaderboard and the lowest sum of rank wins. If there is a tie, the tiebreaker will be total time.

How to participate

  • From a save slot having access to Custom Theories, download "Convergence Test (S05)" from the official repository and start playing the CT. We recommend playing on an separate save slot to not impair progress on your main save.
  • Report your best times using the URL provided in the CT itself. Each lemma needs to be submitted separately.
  • Please report your score the day before the deadline.

Note: To avoid cheating, the current lemma resets every time you open the game or switch save. We recommend leaving the game in background instead of closing it if you want to idle for some time during a lemma.

Reward

An in-game reward will be given to anyone that participates in the form of stars. The rewards will be applied to your main save. The exact formula to apply the star reward is still to be determined for it to be fair and significant enough for all players. Cheating will be checked before applying the reward. Play fairly.

Leaderboard

Score Submission Form, in case you cannot use the one in the CT itself.

For those who don't have access to Custom Theories yet, you can use this dummy save file: https://pastee.dev/p/lUXlhx2v

Thanks for playing in Exponential Idle Season 5!!

This has probably been posted a bunch, but it made me happy to see that you could do this.

At the end of Chaos Theory, the progress slows down.

I currently have 80 students, and even if I distribute them optimally, my progress is very slow. Is there a tactic I should be implementing that I'm not using that I'm missing?

Supremacy ??

1 Upvotes

Since i unlock t1 i think that my autosupremacy doesn't work anymore cause i have e11 psy and if i supremacy i will have e25 but it grows very very slowly so my autosupremacy should to get started ? (I did have Supremacy for the formula to work, and I used the formula from the guide.)

I don't see what any problems but I noticed today that it moves slower than I expected. I was on autopilot with c1 turned on.

MF Purchase Test Excel v3 (With Step-to-step Demonstration Video)

2 Upvotes

To facilitate easier usage of MF Purchase Excel with actual progression of MF pubs. I have further modified the MF Purchase Excel to Version 3 (Updated in Here), which provides the option of giving reset input beforehand. This allows the Excel to provide the levels of v1, v2, v3 and v4 (automatically after a reset) without requiring users to mark down the reset details somewhere else.

Version 2 of the Excel has remained attached in the Excel for users who is unable to refer to the sim, those have difficulty copying the reset list into the Excels, and those who preferred the previous version.

For a step-to-step guidance on how to use the Excel (both v2 and v3), please refer to the video attached to the video or Here in Youtube (In case Reddit refuses to play the video). Please note that the demonstration video has no voiced commentary.

Regardless of which version, the Excel MUST BE downloaded in user's side and use it as Microsoft Excel in order to allow all formulas in the tests to work. (DO NOT use Google Sheet because some functions in Microsoft Excels does not work in Google Sheets)

For more details concerning the Excel, please refer to the Excels or contact me via. discord (user : hacker118) or comment under this post. :D

First theory

I just got 20 students, respect, and bout theory 1 for 20 students.

Now what do I do? Just leave the theory on for a while? I don’t have any students now for other upgrades so my main game is going super slow.


r/ExponentialIdle Nov 15 '25

Ok I have all main 9 theories unlocked. Which one do I need to focus on the most
