BetFair Big Brother : Refresh rate has to be moderated

I've been contacted by BetFair with a polite request to set our minimum refresh rate to 0.2 sec.  

It turned out that this is one of the requirements to all software that works through the API:

Application Security Certification

Your application should not make any more than five market prices requests, per market in any one second.

It appears that despite our warnings an increased number of customers started complaining about exceeding the request limit and thus being liable to charges. Obviously this has something to do with setting the refresh rate to 0.1 sec - at this rate it is sometimes impossible to maintain efficient request limit control.

So I'm very sorry, but we'll be putting the min. refresh rate to 0.2 sec in the next software update.

That's find Oxa. 0.2 is just perfect.

We've updated all the setup files today: from now on the refresh rate can't have a value less than 0.2 sec. It is one of the recommendations of BetFair to keep within that limit, otherwise it is next to impossible to prevent you going over the request charge cap.

I've always had imposed a 0.20 seconds, because I have been punished?

Besides the charges ... 0.2 pers second is what betfair refreshes the api data at ... anything lower is pointless as you will get the same results set.

Not sure if there were changes made over the past few weeks but have they done something with the refresh rate? Looks like something is changed but I can't seem to pinpoint where.
