Missing Samples in a ThrottleStop Log: Avoid False Temperature Conclusions
Identify logging gaps, session interruptions and unequal sampling before calculating or comparing temperature summaries.
Home / Guides / Missing Samples in a ThrottleStop Log: Avoid False Temperature Conclusions
Direct answer: A gap is missing evidence, not evidence that the CPU stayed cool. Check timestamps and session events before interpreting averages or apparent temperature improvements.

Inspect the timeline before the numbers
Open a copy of the log and inspect its time coverage. Preserve the original file unchanged. Record the intended session start and end, then compare those with the available entries. Check whether sleep, an application restart or a stopped logging session could explain the gap. Do not fill missing records with the last value merely to make the graph look continuous. That substitutes an assumption for an observation.
Sampling and duration affect summaries
If samples are unevenly spaced, a simple average of rows is not automatically a time-weighted average. If a high-load section was not recorded, the available rows cannot establish the whole task's thermal behavior. Likewise, a short log and a complete long run are not equivalent evidence. Mark the sections with sufficient coverage and keep conclusions limited to them. Do not treat an empty interval as zero temperature.
Connect gaps to system events
Keep notes of sleep, wake, reboot, workload starts and manual logging changes. Check whether the main application reading also stopped updating or whether only the recorded output is incomplete. Those are different failures. If the display remained responsive but no file appeared, verify the selected location and permissions. If readings froze after a system transition, use the existing sleep or sensor troubleshooting guide and check release notes.
Work with copies when analyzing
Use a duplicate file for sorting, filtering or spreadsheet import. Check that timestamps and numeric fields were interpreted correctly and preserve the timezone when it matters. Some import tools can change date formats or interpret a value as text. Document any rows you exclude and why. Keeping the original allows a support contact to inspect the exact evidence rather than a cleaned file with unexplained omissions.
When a new session is the better answer
If the gap covers the critical part of the workload, repeat the ordinary task after resolving the recording issue rather than extrapolating from surrounding values. Keep the previous session labeled incomplete. A repeated run can improve evidence but does not recreate the exact earlier state. If the original event involved instability or shutdown, prioritize the symptom and do not repeatedly stress the machine just to produce a complete chart.
ThrottleStop-specific interpretation
Record the selected profile and the available Limit Reasons indicators alongside the observation. A thermal indication, a power-limit indication and a low utilization reading answer different questions. Do not raise a power or current limit, disable BD PROCHOT or import an undervolt just to make an indicator disappear. Supported controls depend on the exact processor, firmware and system policy; a visible field is not proof that a requested setting was accepted.
Practical checklist
- Preserve the original log and analyze a copy.
- Check start, end and gaps against your session notes.
- Determine whether readings or only logging were interrupted.
- Limit summaries to the coverage actually available.
- Repeat an ordinary observation only after addressing the recording problem.

Questions and answers
Can I fill gaps with the previous reading?
You can label an explicit visualization assumption, but it is not a measured sample and should not support a safety claim.
Does a lower average from an incomplete log prove improvement?
No. Missing workload intervals can bias the summary.
