Canadian High Interest Savings Bank Accounts

I've got a question here about the number of total referrals allowed by ICICI.

I see all the referral sent for the promo 20$ are all listed on your ICICI account, they're all listed with their corresponding number even included on the referral number.

I was wondering what defined the the maxium limit 25 (which I'm far from being)?

Is it the number of referral you sent
or
the number of people that you have referred and who have signed up and sent a 100$ check deposit and hence, the 25 x 20$ promo bonus you have received for referring?

With 6 referrals to my count, we'll have to work on our patience for a while.
