um..sorry I clarify a bit for example the APY I se... @beefyfinance

The APY you see from PancakeSwap is 10%. If you use Beefy for the same pair, you will get a lower APY of 9.45%. This is because Beefy charges a 4.5% fee on all trades, which is then subtracted from the APY you would otherwise receive. This means that the APY you receive when using Beefy is (10% * 94.5%) = 9.45%.

The later calculation is correct
