No, although you cán do this with CardRunnersEV.
I've made a list for you:
Top 5%: 29% chance of bd flushdraw
Top 10%: 29% chance of bd flushdraw
Top 20%: 29% chance of bd flushdraw
Top 30%: 31% chance of bd flushdraw
Top 40%: 30% chance of bd flushdraw
Top 50%: 30% chance of bd flushdraw
Top 75%: 30% chance of bd flushdraw
All hands: 30% chance of bd flushdraw
And here's the stats for 2 card backdoor flushdraws:
Top 5%: 8% chance of bd flushdraw (2 crd)
Top 10%: 9% chance of bd flushdraw (2 crd)
Top 20%: 11% chance of bd flushdraw (2 crd)
Top 30%: 13% chance of bd flushdraw (2 crd)
Top 40%: 12% chance of bd flushdraw (2 crd)
Top 50%: 11% chance of bd flushdraw (2 crd)
Top 75%: 12% chance of bd flushdraw (2 crd)
All hands: 10% chance of bd flushdraw (2 crd)
As you can see, it's not exactly the most fascinating of all stats.
It's only at the top 5% and top 10% for 2 cards backdoor flushdraws that there's any remotely significant impact, and this is because the ratio of suited and paired/offsuit hands is significantly different (a pocket pair or offsuit hand can never become a backdoor flushdraw because both cards are of a different suit).
Basically there's 2 things that decide whether or not a hand is a 2 card backdoor flushdraw:
1) What is the chance of holding a suited hand?
2) What is the chance of a single card of that suit coming off on the flop?
The answer to number 2 is always the same, namely 41.6%, regardless of the hand. So the only real factor of significance is the chance of holding a suited hand. And that chance is also always about the same, regardless of the range.
Anyhow, no, Flopzilla does not show this stat for unknown flops.
