How to test that latency setting is correct?

Hi to All,
 
I've searched for test/check methods of latency setting is correct, but maybe it's me, have not found working link, method.
 
***
I am using Sonar Platinium with Focusrite Scarlet USB soundcard and successfully configured ASIO in and out. All is working.
I can open the ASIO panel and set sample rate and buffer size, and I also found the "Sync and Caching" in Sonar preferences and see that latency was set according my ASIO driver settings. (Use ASIO reported latency) 
 
I would like to to the simplest recording: Import a backing track, then play and record guitar over it. I did it successfully, by sending the imported backing track output to my Focusrite soundcard.
 
When playing back the recording and the backing track it sounds good and in sync, but I would like to check somehow more exactly that the applied latency compensation is correct. 
 
Is there any professional way to do this?

It's called a loopback test.
Patch your output back to an input.
Use a frozen drum track with a good transient spike.
record this to a new audio track make sure to leave input echo OFF 
Now zoom in and look see.
ASIO is always right on but other Driver modes not so.

Even ASIO drivers can misreport latency. This is why there is a manual adjustment for ASIO in preferences. There are a couple of methods using loopback tests to verify the accuracy of the reported latency. CEntrance makes a tool to simplify the process. Scroll down on this page for the link to register for their Latency Test Utility download.
