Hold4BUSD.swapAndLiquify(uint256) (#562-592) performs a multiplication on the result of a division:
-split_M = Percent_Marketing * 100 / (Percent_AutoLP + Percent_Marketing + Percent_Dev) (#577)
-BNB_M = BNB_Total * split_M / 100 (#578)
Hold4BUSD.swapAndLiquify(uint256) (#562-592) performs a multiplication on the result of a division:
-split_D = Percent_Dev * 100 / (Percent_AutoLP + Percent_Marketing + Percent_Dev) (#580)

Consider ordering multiplication before division.

Pragma version0.8.10 (#10) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.10 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
