Depending on the chosen Tone Profile and payload size of your transmission, your detection rates will vary. Throughput of Standard2 profile is 33.3 bits/second, 66.6 bits/second (wideband). Throughput of PKAB2 profile is 1000 bits/second, 2000 bits/second (wideband). To read more about the different tone profiles, check out this article.
For example, a Standard2 Tone (wideband) with a payload of 6 bytes will transmit in 1.7 seconds. A PKAB2 Tone with a payload of 6 bytes will transmit in 0.43 seconds.
