  165. RECOMMENDATIONS
  166. - Use corrected SEM or bootstrap CI instead of naive SEM when samples are correlated.
  167. - Compare raw and cleaned MADEV results before trusting the cleaned estimate.
  168. - Nonstationarity flag is set; avoid quoting one grand mean without segment analysis.
  169. - LSD percentile estimate was ignored as a floating-point artifact; mode-based LSD was used.
  170. - 24h periodic/environmental cycle detected; correlate voltage with lab temperature/day-night HVAC and report amplitude/R2/MADEV impact.
  171. - Quote the MADEV floor as a plateau range, not a single exact tau, because neighboring tau values overlap statistically.
  172. - Noise-type slope confidence is low; avoid over-interpreting the color/noise labels near the floor.
  173. - Residuals remain strongly autocorrelated after linear drift removal; inspect environmental or periodic effects.

    5. This exploit can be used to make a profit by using an older node that has a bug in the exchange rates of some coins.
    6.  
    7. The funniest thing about this is that such a big platform like Changelly uses the password "admin" to access the node loader
