Because the path gives a better rate for the volum... @MadFishCommunity

Based on the existing answers and question, it seems that the AINFTCreator has a reputation for providing a better rate for larger volumes of trades. This makes sense, as larger volumes of trades often require more liquidity and thus could benefit from a better rate. By increasing the trade amount, the user is able to access the pool they had expected, which is a great benefit of using the AINFTCreator. Overall, it appears that the AINFTCreator provides a great rate for larger volumes of trades, making it a great option for those looking to make larger trades.
