Superpilot........
172 driver raised some excellent ideas.
I am a crusty instructor, and try and encourage CPL candidates to have a few CPL lessons (accuracy type-while hour building)before they start the serious stuff so they can get up to speed with accuracy, methods, etc etc.
It is more than just an 'hour' thing, the CPL is a professional licence, like 172 driver stated, you need to have a good subject knowledge.
Know the rules backwards, and find out what employers are looking for....
A good instructor will get all your PPL stuff 'up to speed' before starting any CPL stuff, just launching straight into a lesson, like say, max rate turns, when the steep/medium turns are not up to scratch, is just a waste of money.
I find that attitude(the pilots, not the aircraft!) means a lot to a prospective employer, some CPL's never make the grade, others get hired with early hours, because they display the right attitude.
Enjoy your hour building(and CPL training) use the time wisely.
Good Luck from New Zealand.
