What is the benchmark you usually define for Install Validation fraud percentage with your affilliate partners?

Once you activated the anti fraud tool from Singular, you start evaluating your traffic. We already know that traffic from SRNs and Programmatic is different than the traffic from Affilliate parntners, but at the time of looking at this metric called Android or iOS install Validation, it´s usually hard to define a benchmark. Of course one will always try to keep it at the lowest percentage, but it might end up in killing volume, and that might be counterproductive, as much of the volume of these networks usually has good quality, and this metric is not about attribution fraud, but "event" fraud.
