Thanks for comments.
Yes I do watch dynamic meters. Also I have adjusted all the tracks in my reference library to the same integrated loudness of -16 LUFS. And when I mix I always try to be in same RMS levels with them, so that I won’t be fooled by loudness, hopefully. During the mixing I typically abide around -16-20 RMS.
So, normally when I mix I have plenty of headroom, but in some cases I add a bit heavier pseudo mastering before I send it. Personnally I prefer a mix with more dynamics, but for some reason in most of the competitions that I’ve followed the winners have been extremely loud, although quite often it has been said in rules that it’s not loudness competition. So in this case I just made a guess and decided to add some competetive loudness. But for example in currently active Hofa-competition I decided to send an unmastered version.
On the other hand, even if one is ”dynamic lover”, heavy homemade mastering is good test for the mix. It the mix is unbalanced, it cannot go through loudness war limiters without changing drastically. So ”loudness test” belongs to me to similar checking routines as for example ”mono test” and ”small speaker test”.
