How many times should the highest object be measured to calculate site to crest?

To accurately calculate the site to crest measurement, the highest object within the area needs to be measured multiple times. This approach accounts for any potential inconsistencies in the terrain or measurement technique and ensures that an accurate average is obtained. Measuring the highest object three times allows for better reliability in the data collected, minimizing the potential effects of any outliers or errors from a single measurement.

While measuring once might give a quick assessment, it lacks precision, and increasing the number of measurements can introduce unnecessary complexity without significant benefit. Measuring twice could potentially catch some variability, but it may still not fully capture any discrepancies. Thus, the best practice is to measure three times to ensure a comprehensive and accurate assessment of height in relation to site to crest calculations.
