yeah, well i dunno i play most of my mixes by ear and i dont really indulge in specific mastering at the end of each track, i master as i go and then just tweak the mix at the final stage really, just me personally but i find following most standard procedures dont always get the results that i want, for me personally. If it's sounding sweet on the monitors and there are no obvious mistakes to fix up then i try not to worry about things like this too much, as i find myself worrying about even more less fundamental things and next thing its production information overload time and my brain ultimately shuts down :)
