Don't grease the screws that hold the levers on the braze on bosses. Clean the threads then apply blue loctite before reassembling. Take the levers off and make sure there is no lube or grease on the friction washers. Reassemble dry. The 2 things might slow the slipping down a little. I hate to say it but I gave up on Campy downtube shifters over 10 years ago for this exact reason. Mavic retrofrictions are much better.
