Full disclosure, I’m a co-creator of the site, hahah. A few other notes for people who are curious about where their cycles are going:
This under-appreciated forum post from October seems to be the latest on cycles insights, which would provide much greater visibility into compute vs memory related burn, etc., or even function level granularity on cycles burn: Canister Insights – Richer Metrics for Developers
Also, for future, you could add your blackhole canisters to cycleops (before blackholing them) to get lots of observability metrics, like burn over time, memory usage, etc. Full disclosure again, I’m co-creator there, too.
