Please, can you help me to understand?

As user I'm suggesting to implement a new method to manage capital called Fixed Ratio.
Fixed ratio position sizing was developed by Ryan Jones in his book "The Trading Game," John Wiley & Sons, New York, 1999. Based on an equation presented by Jones, it's possible to derive the following equation for the number of contracts in fixed ratio position sizing:
N = 0.5 * [(1 + 8 * P/delta)^0.5 + 1]
where N is the number of contracts, P is the total closed trade profit, and delta is the parameter discussed above. The carat symbol (^) represents exponentiation; that is, the quantity in parentheses is raised to the power of 0.5 (square root).
In fixed ratio position sizing the key parameter is the delta. This is the dollar amount of profit per contract to increase the number of contracts by one. A delta of $3,000, for example, means that if you're currently trading one contract, you need to increase your account equity by $3,000 to start trading two contracts. Once you get to two contracts, you need an additional profit of $6,000 to start trading three contracts. At three contracts, you would need an additional profit of $9,000 to start trading four contracts, and so on. For stock trading, a "contract" can be interpreted as a fixed number of shares, such as 100 shares.
