The relationship between orifice (spray opening) size and PSI is a question of balance. The recommendations on the chart are for optimum performance. If you want a wider pattern with a less powerful spray you can go up a bit in orifice size; if you need a more concentrated spray (but a smaller pattern) you can go down a bit in orifice size.
Please be careful, though- too large an orifice will be ineffective, and too small an orifice for your pressure washer's PSI could cause the quick connector or nozzle to fail.
