"I" think the effectiveness of calls is directly proportionate to your herd dynamics.
You can take the quotes off the I and make that a "We."
Where I hunt in Canada I would say blind calling, any method, works about 7% of the time. Sight calling works about 75% of the time.
In WI, blind calling works about 3% of the time and sight calling works about 10%.
They are two totally different herds and respond totally different.
