What I was really hoping to see is how the final statement looks when you execute it.

It's different if it looks like this

INSERT INTO test(col1, col2) VALUES( @param1, @param2)

INSERT INTO test(col1, col2) VALUES( @param1, @param2)

INSERT INTO test(col1, col2) VALUES( @param1, @param2)

INSERT INTO test(col1, col2) VALUES( @param1, @param2)

INSERT INTO test(col1, col2) VALUES( @param1, @param2)

Than if it looks like this

INSERT INTO test(col1, col2) VALUES

( @param1, @param2),

( @param1, @param2),

( @param1, @param2),

( @param1, @param2),

( @param1, @param2)

I'm not sure if I'm clear enough.

If you're just testing, then just test, and test several times to obtain consistent results because times can vary depending on the workload of the server.
