The 650 $YIELD burn cost is the investment basis for APR calculation.
APR moves within the base range depending on global participation.
NFT upgrades increase APR linearly.
Early Epochs offer the largest boost for Locked rewards.
Staking duration does not affect APR — only global activity, NFT levels, and Epoch multiplier matter.
