Each one counts as an individual $10 tourney as far as BRM goes.  However your volume is likely increasing so you'll feel a greater effect from variance.   For example during double gtd week I found I was playing 15 tables as opposed to my normal 8.  I dropped some of my higher and lower end stuff but at the end of the day my daily spend was higher.

It was too much variance for me.  Theoretically it shouldn't make a difference but watching it go down faster (i bricked that week) so I felt a psychological effect.

Since then however I've been using it to advantage.  I've dropped almost all tourneys >$75 because I don't think the value is there that I can get from going 4x on the $26 10pm EST.  So my overall spend has gone down because there are more value tourneys at the bottom end of my buyin range and i've cut out the higher stuff where my EV wasn't as big.

The one thing I am still trying to wrap my mind around though is how does this affect your chances, odds, not really finding the right words, but if you are buying in for 1 or 2 entries, and others are buying in for 4 entries to the same event, aren't you at a huge disadvantage against these players?  Is there some type of terminology here that I may not be using to better explain myself on this subject?

Not really.  The only disadvantage is a tiny chance that your stacks merge at some point.  one stack with 60k is worth less than 2 stacks with 30k.  However, stack merges are going to be rare in large field events.

But if you have 4 shots against someone that has 1 shots you aren't at a disadvantage.  They are just playing less tourneys than you.  This would only matter if you give up your chance to finish with multiple spots in the final table.  Being amongst such big fields this is just very unlikely to happen.
