You are pretty close with the specification you mention in real-life scenarios.
It fits well with the broadband connections that were the dominant speed at the time of the release of the RAP-2... and even today I see all kinds of broadband connectivity at, for instance, 3Mbps:1Mbps (xDSL)...e.g. the RAP-2 handles that and a bit more full encrypted.
That being said, for locations that need more encrypted throughput, I have put the RAP-5 into place.
