Once the R/D cycle is triggered, Spectra will give "selected R/D time" to the process, regardless of the number of targets in ground. If you give Spectra 100 R/D units, it will use every one. If your detector passes over one target, you must burn 100% of the R/D units before Spectra can process another target. Shorter R/D times can accommodate a denser target field. How long Spectra has to process the first target, and then be ready to process a second target. Lower numbers = SHORTER delay. Higher numbers = LONGER delay. Faster recovery doesn
