Yes, others -- like me -- are just like you. Adjusting the saddle -- fore/aft or height -- by just 5mm results in me losing so much power, that it can literally drop my speed IN HALF while going up a 10%+ grade!!! At least in my case, it can also affect cockpit positioning. At my current saddle fore/aft, if my reach is more than 56cm (saddle tip to bar) or the bar is more than 6cm below the saddle -- even by 5-10mm -- my power drops 20%+. If I move the saddle 5mm forward, that power loss occurs if the reach is only 53cm, and bar drop is only 4cm. Go figure!
