Groups and Integrations calculator doesn't provide an option to select 1 amp readout (4 amp readout is assumed).
APT has a 30-group limit on NIRCam that isn't considered in the G&I calculator.
This combination of issues makes it impossible to plan observations of fainter (K>9) stars using the tool.
One solution is to let the user decide how many amps to use (with a warning to switch if the ideal number of groups is > 30). The other solution is to use some logic to pick the appropriate number of readout amps.
