If you're planning on negotiating a pay rise, you'll need more than a 4 rating and above average utilisation. You've just had a promotion and with it will come a nice bump in pay.
The way to drive increases in your salary probably isn't to just ask for pay rises at the end of every performance year. It's more about making timely and well thought out tactical moves between firms and performing well enough to get promoted ahead of your peers.
That said, if you think you've got a case (and I'd suggest you think of a better one than the one you describe) then it's not unheard of for pay rises to be given.
It normally comes as a result of handing in your resignation with a better offer that is not directionally too different to what you would be doing at Deloitte. Even then it will depend on the relationships you have in your practice, your performance, your current engagement and crucially the market.
In these cases I have heard of people given immediate pay rises, loyalty bonuses and promises of early promotions. Be careful when you choose to cash this hand in though. Make sure it's part of a longer term career strategy.
