It’s not referring to 6 or 7 WEEKS !!
It means try the method 6 or 7 times in as many minutes .
So if the snake doesn’t strike the first time you have to reheat the mouse/rat with the hairdryer and offer the food instantly again ... then repeat as many times as you can be bothered . Too many offer a cool mouse ONCE then just give it up as a bad job . That’s why I always emphasise the method so carefully.
