It's impossible. I generally play 4 tables of 8 or 10 handed. After day 2 (I missed day 1) of the 15th-31st $100k race, I pinged support to see how many hands I had on that day, having played for a few hours.
I had about 980, the leader meanwhile 18,000+
Basically, if you're not playing short handed games with at least 8 tables, for probably over 10 hours a day, just forget the promo, as you've no chance whatsoever.
