Example in e-book is bad with very saturated niche, but it may work with less saturated ones. Payment proof in e-book pretty time-consuming to fake so it seems to be legit.
And yeah, there is no $1k/day bullshit. The author made $278 in 22 days and there is no info about how hard did he scale this. Network offers rates like $2 per install in US, $1.5 in GB, $0.5 in CA and AU. For other countries there are shitrates.
About payment schedule:
Quote: Our automatic payment cycle is biweekly. Money earned from 1-15 will be paid at 16th-18th and money earned 16-31 will be paid 1st-3rd of next month. If payment days are not a business day, then payout will be send on the following business day. However, if you reach your declared minimum, you can request payment manually - in this case your earnings will be paid within next 2 business days.
As for me, I'm currently lurking in youtube + cpa, and I found some useful tips for me.
