I think the y axis: "% Bugs" in Fig. 1 has an incorrect scale. It doesn't add to 100%.
Also, it doesn't seem consistent with the claim: "Bugs discovered through Instabug are most likely to be resolved within 24 hours of being reported"
Also, it doesn't seem consistent with the claim: "Bugs discovered through Instabug are most likely to be resolved within 24 hours of being reported"
From the graph of total bugs vs time. It appears like at the current time ~10% of all bugs have been reported in the last 30 days. Even if all those bugs were magically fixed tomorrow, that would only be ~20% of bugs within 30 days so we can claim:
"Bugs discovered through Instabug are unlikely to be resolved within 30 days" and "1.5% of bugs discovered through Instabug are likely to be resolved within 24 hours of being reported"
The confusion on the second point hinges in "most likely". You're likely interpreting that as the expectation of resolution time whereas they are using maximum likelyhood estimation. MLE is rather useless in this case, but it is technically still correct.
Graphs are for asking better questions, not for making decisions.
Such a bad plan in fact that Mark Twain has a joke about it.
