What those calcs say and what works in real life aren't the same sometimes.
What you described means that you need to slow your beer down. Get 12ft of 3/16" beer line. Let it get cold after installing it. See the difference.
BTW, you probably already know this, but it's worthy of mention. Treat the faucet like an on-off switch. A partially opened tap will create plenty of foam even if all else is good.
