SOLIDITY ADVICE REQUEST

 I want to calculate the interest rate for a token with a fluctuating market price given by a bonding curve. 

Currently, i timestamp the price whenever it changes and append into an array; any ideas on strategies that avoid this kind of state bloat?

How would i safely store timestamped price changes off chain? How could the contract verify.

Why does the rate need to be onchain? Otherwise store the observation in a mapping as you avoid gas overhead for checking array length validity in solidity
