You seem to be working too hard. An RSS feed isn't designed to be over-written completely every time you update it. That's why items have a GUID. Just add your new items, and leave the old ones there too, for as long as you want.
Obviously the file will get too big if you leave them there for weeks, but you seem to be addressing the wrong problem -- "a certain RSS reader has a certain lookup rate and I need to match that" -- RSS is designed for agents to come and look at the feed whenever it suits them, and to figure out what's new for themselves, based on pubDates and GUIDs.
Nobody says perl looks like line-noise any more
kids today don't know what line-noise IS ...
