What timing do you think is optimal to text Subway in the 5th inning? Do you text as soon as prompted, or do you wait 30 seconds to a minute?

I do it right after the 499th person.

I used to have a phone that would allow me to send a text to 10 recipients manually so I would send the same text using that number listed 10 times, and then just kept resending it. Realistically, I could shoot out 50 texts to the contest number in a minute or so and I imagine other people do that as well- I say send your texts right away. Full disclosure- I won that gift card way too many times
