Hello good morning everyone, I'm doing some liquidity and swap tests in uniswap v2 goerli and I get some strange results, because a user initially spends an amount of eth for token A, then change token A for token B and then token B for token A and get more eth than initially spent this makes sense?
Here are the txs
