If you read my project then you know what i want

HI i need to finetune my scrapingproject.
we have a 3 provider proxysetup that continously looks (3x times per second) if new ads are available, and if so get the phonenr from api of that ad sent to a phonesystem.
Now we have the ad timestamp available on site, and at the end the timestamp at our server when we get the ad. There is our problem, this time differs between 0.5 – 7 seconds. Our datafetching time is less then a 0.6seconds.

I dont understand if we look 3 times a second with proxy, and fetchtime 0.5, we should be able to get the phonenr within one second. Any one has a solution for this.
