I posted a similar question yesterday, and received similar responses. BTW I PIF all my cards weekly...
My very unscientific survey leads me to the conclusion that the payment pattern AMEX (and every other creditor) likes is:
1. Use their cards early and often
2. Pay them (on time)
3. Repeat steps 1 and 2.
Whether you pay weekly, bi-weekly, or monthly I do not think matters so long as they're getting paid. The reason I say this is no one (correct me if I'm wrong) has actually posted a 1st hand account of getting AA/FR due to multiple payments. It's all 2nd and 3rd hand mish-mosh, which leads me to conclude this may be more myfico mythology than reasoned fact.
And if a company decides to AA/FR you for paying your bill...well that's just dumb business practice (and a good reason to have cards with several different banks). More concerning to banks (I would think) is people monkeying around and paying with Bluebird/Vanilla cards or by other means. That may throw up some flags. But paying FROM a regular bank account in your name TO a credit card in your name...this seems like a pretty low risk proposition to me.
Remember at the end of the day, you are their customer...banks should be trying to make you happy, not the other way around! 
But as Dave said, unless you work at AMEX HQ, this is all pure speculation.
I feel a little bit better reading others' comments this morning. I was approved 40 days ago and have had the card a total of 33 days. My highest util before PIF immediately was 46% (didn't let that report). That was a payment of $922 before the first statement cut. As of today, DW and I have used/swiped the card 56 times. While some comments on this thread make me worry a bit, I'm going to continue what I'm doing. The common sense side of me says the more usage, the more $ AMEX makes and, in turn, makes me valued as a customer. No use = no profit for them. Am I screaming risk, who knows? Yes, maybe it's a bit overzealous on my part with SUCH high usage but at the end of the day, high usage on a smaller credit limit and paying it multiple times to keep the util down (and hopefully risk assessment down) and showing them I'm not running up debt but rather using their card ALOT for their profit and my rewards should make them happy. If they FR me for too much usage, simply put, they're out of their mind.
And those that bring up the Everyday product make a good point. Why would they create a product and give incentive on a high number of swipes/transactions if they don't like tons of usage? If they check on me today, tomorrow or anytime in the future, they are going to see high usage on my Citi card and their card, both always reporting a zero balance (with all other cards at zero, too).
Two side notes - DW and I don't eat out. We are very health conscious and eat every meal at home and many times, organic. The reason I got the BCP was solely for the purpose of groceries and our overly high spend due to eating habits. We likely spend way more than the average couple at the grocery due to diet, thus, making the BCP an extremely valuable card to us. Lastly, I'm questioning whether or not to try for the 61 day CLI request. I almost want to hold out and see if they give me an auto CLI first. I've seen it on a few threads here in the recent past. Hopefully, I would be a good candidate.
Have to remember this forum has been around since the mortgage crisis, and the market was a completely different place then.
Some of our long-held conventional wisdom came from that era, and has been passed down over time. If something seems wierd or laughable with the current market as it's been for the last 2-3 years, there may have been solid rationale for it previously: and non-zero chance we could go back to it at some point.
Not saying that walking on eggshells around Amex is necessarily part of that, but FWIW people were doing that with the majority of lenders as they were all reducing their exposure faster than their stock prices were falling at one point.

That is a good point, one I haven't considered. I didn't get my first credit card until 2010, after the first (worst?) wave of big bank freakouts. I'm pretty fortuate in that regard.
That being said, I think it's time for at least some of the myFico lore to be abandoned.
FWIW, I just came home from work today to a PRG 50K bonus targeted prequal offer after 1K spend in the mail. It's probably nothing special (I don't know how much 50K MR points are worth) but I'm feeling okay about my usage. One would think they wouldn't offer a second card to someone where usage or multiple payments is an issue.
I, like Stralem, didn't think about the days Revelate mentioned. It's a very good point and explains some of the 'tread lightly' responses.
