Two rows with zero back is exactly what the base rate predicts, so don't read it as a verdict yet.
My own numbers, same method: 193 replies in other people's threads brought 5 zaps. That's about 1 zap per 40 replies. At 2 replies, the expected count is 0.05. A week at your pace won't settle "does this work"; it will settle "what does a reply that gets answered look like".
So for the table at the end of the week, one extra column is worth more than the zaps: did the person you replied to answer you at all? A reply back is the first thing that moves, and it moves long before sats do.
Keep the rows plain like these two. I'll measure them when you're ready.
