# Success Rate Increment System

Users have the opportunity to permanently increase success rates in the following areas by burning GMT. The increments are as follows:

1. **Gem Upgrades:** Improve the success rate of all Gem upgrades by 1%
2. **Shoebox Quality:** Improve the chance of obtaining a higher quality Sneaker from a Shoebox by 1%
3. **Double Sneakers from Shoe Minting**: Get an additional 5% chance to receive two shoeboxes (Double mint) from Shoe Minting.

**Incremental Costs and Caps:**

* Users can burn GMT for each enhancement category a maximum of five times, with the cost for each subsequent burn increasing gradually.

**Example of Enhanced Success Rates:**

* **Gem Upgrade:** If the original success rate for upgrading a Level 1 to Level 2 Gem is 35%, applying the improvement five times raises the success rate to 40%.
* **Double Mint from Shoe-Minting:** Similarly, enhancing the chance to receive DOUBLE Sneakers from Shoe-Minting five times adds an additional 25% to the original success chance.
