It seems to me he might be saying since the DOS actively monitors dosage quantities in ml measure, it would be one thing to adapt the programming to automate adjustments based on Trident values. With another pump that does not store a calibration value in the Apex (GHL, BRS...), the programming would be somewhat unreliable and untrustworthy due to the dosage quantities being unknown.Hmmmm so basically you are saying it would be best to get the DOS if you want to allow the trident to correct alk swings ?
