How long before triple texting a girl who hasn't responded in days?

Day 0: girl responds for the last time. You reply to her message.
Day 1 (no replies): you double text her at at the end of the day (24 hours later).

Should the triple/last text come at the 2nd or 3rd day?

I want a real answer. I don't want answers such as "you shouldn't double or triple text at all, just cut her out of your life".

Thank you
