The top 5 really kick the NDX and QQQ up/down the hardest. Look at the market cap..but when it comes to max pain the amount of stock to be bought or sold will effect a big cap less than a small cap..so you don't need to weight the max pain, but do bring yahoo into the picture, maybe AMZN too as the nuts while smaller have been leaders both ways latly.
