Table 1 Deviation of predicted prey ingestion rates from the observed using the different segmentation methods and different segment lengths and ARL0-values. In most cases, the confidence intervals (estimated from 100 simulations) include 1.0 (no deviation), indicating that both methods predict prey ingestion rates that are very close to the true value
