            if (trueBloat < falseBloat * 2 - 10) {
                // inline the false branch, guard with the true branch
                return syntax.Else.Statement.Statements().Prepend(
                    syntax.WithStatement(syntax.Statement.BracedTo(syntax.Statement.Statements().Concat(new[] {allowedJump})))
