Both references label the route unavailable. This is a source report, not a live check of your server or event shop.

Ability, targets and limits

Calculator Wiki describes consuming a random garden mutation and spreading it to other random fruit.

Do not model a trigger as a fixed amount of income. The selected mutation, affected fruit and any exclusions need current observation.

Weight and cooldown

Calculator Wiki publishes a weight-dependent community timer with a 15-second floor. Use the displayed interval instead of assuming every T-Rex has the same cooldown. Supporting reference.

If your measured interval is 20 minutes, one hour contains three complete triggers. Log which mutation is removed and where it spreads; three triggers alone cannot establish the number or value of useful changes.

What do the reported hatch odds mean?

Using the reported 0.5% Dinosaur Egg chance, 100 eggs give about 39.4% probability of at least one T-Rex. Reaching at least 95% would require 598 eggs under this model.

This is our calculation: 1 − (1 − p)ⁿ. It assumes identical, independent chances with no pity mechanic or changing luck. A 95% threshold is not a guaranteed hatch. Check the displayed chance before using it.

In the hatch tool, enter 0.5 for target chance (%), then your actual egg time, count and cost.
