I totally disagree as I've NEVER had an issue with giving an auto full feedings,they will happily match a photo in size(4week veg),and appetite.
I also do not follow manufacturers guidelines,I have a little chart which has served me pretty well to date with auto's and photo's.
The auto's of a decade ago ie lowriders could not handle a full dose,but today's auto's can and will,maybe try it.
