- `AvgIsPresent`: `SamplesPresent / TotalSamples` (0 when `TotalSamples` is 0).
- `AvgVcpuCount`, `AvgRamGB`, `AvgProvisionedDisk` (daily): `sum(values_per_sample) / TotalSamples` to time‑weight config changes and prorate partial‑day VMs.
- `PoolTinPct`, `PoolBronzePct`, `PoolSilverPct`, `PoolGoldPct` (daily): `(pool_hits / SamplesPresent) * 100`, so pool percentages reflect only the time the VM existed.
- `CreationTime`: only set when vCenter provides it or when a lifecycle cache `FirstSeen` is available; otherwise it remains `0`.

Monthly aggregation builds on daily summaries (or the daily rollup cache):
- For each VM, daily averages are converted to weighted sums: `daily_avg * daily_total_samples`.
