- I believe all issues do not provide a sufficient proof that this latency lags can cause a dangerous arbitrage - Sponsor Comments - There is no issues with small lags if used in liquidity pools for example because of fees. Fees generate spread within which price can be lagged. - Looking at the price charts [here](https://coinmarketcap.com/currencies/savings-crvusd/), there is never a large spike in price (in absolute values), that can be exploited, combined with the fact that prices are smoothed and updates are not immediate - Not even the most trusted oracles e.g. chainlink/redstone can guarantee a one-to-one synchronized value, so in my eyes, the price smoothening protection is sufficient in protecting such issues
