I do not know the upgrade effect
Do not fill it from an unconfirmed list. Use the current in-game text or keep the helper at zero improvement until you can observe a difference.
Choose upgrades by the bottleneck you observe and use the break-even helper without relying on unconfirmed prices, names, or effects.
Quick answer
The best first upgrade is the one that fixes a slowdown you can reproduce: too many return trips, too much walking, frequent control mistakes, a crowded section, or weak team coordination. Observe first, buy second.
Change one habit at a time so you can tell what actually improved the run.
Pick a short shelf area and complete the same loop you already know. Count carried Squishies, return trips, and rough time. Do not activate a new purchase or change the route halfway through. This gives you a baseline strong enough to compare with the next run.
Capacity pressure appears as frequent return trips. Route pressure appears as long walking between useful actions. Control pressure appears as wrong drops or switches. Ability pressure appears when one crowded section repeatedly stalls. Team pressure appears as overlap and slow handoffs. Choose only the problem that repeated.
The official public description confirms upgrades, but it does not publish every name, level, price, or multiplier. Read the live purchase or upgrade screen before spending. Avoid treating a fan list or an old screenshot as a current guarantee.
Enter the cost shown in your game, the reward you observe per run, the improvement you reasonably expect, and the number of runs you plan to play. The helper calculates simple cost recovery and incremental benefit. It does not decide that a gamepass or upgrade is officially best.
Use the same route and controls so the comparison is fair. Update trip time, capacity, or observed rewards with what actually changed. If the bottleneck moved somewhere else, solve the new problem later; do not buy several upgrades at once and lose the comparison.
Try this: Long-term value matters only if you expect to play enough runs to reach the entered break-even point.
Do not fill it from an unconfirmed list. Use the current in-game text or keep the helper at zero improvement until you can observe a difference.
The upgrade may be a convenience choice rather than a quick payoff. Compare it with route practice or capacity changes you can make without spending.
Repeat the original section before judging the purchase; different distance makes the comparison weak.
Rarity or price does not prove that it fixes your current slowdown.
Prices and effects can change; enter what the current game shows.
An upgrade that recovers cost after many runs may not fit a short session.
Choose the option that fixes your repeated bottleneck. Exact named rankings are held until stronger current data exists.
No. The helper uses the cost, reward and improvement you enter from your own observations.
Check the current in-game effect and compare it with how many runs you expect to play. No exact gamepass recommendation is made here.
Test each against the same route and use the observed time, capacity or reward change as the input.
