You'd be surprised how much horizontal cathode current changes with just a few volts difference AC input, it can mean the difference between a hot sweaty flyback and an ice cool happy one. Having said that, I also agree that going through the horizontal circuit setup procedure is essential to proper operation. Beware faulty parts though, the 7 I sold Ed in Buffalo always had cathode current slightly higher than I would have liked. He later told me he replaced the LIN coil and it dropped even father, which I can only attribute to either copper winding breakdown (the wire itself increasing in resistance), or the slug losing permeability over time.
I guess the lesson there is don't assume your flyback is toast because it's drawing more current than you'd like, failure of some other part is always an option.
