Don't know about that...
I do almost all my riding in the Peak District. ~50-150km rides with ~1000-2500m climbing; gradients 2%-22%. Usually climb about 150,000m per year. I do not chase points of any sort...
An average "long" hill here is ~6km, climbing ~250m; "shorter" hills are steeper.
The difference between my Ti "light" bike (9.6kg) and comfortable steel "distance" bike (12kg) is about 15-20 seconds on a "long" climb. (I weigh 95kg, 190cm tall)
I think there are other factors than weight that also affect the feel of a bike. Stiffness, handling, perceived power transfer, position, etc. My "light "and "long distance" bikes feel about the same. My Tourer (13kg) feels and is s little slower and heavier, less responsive (even unloaded) but is very good for eating flattish comfortable miles.
Climbing is all in the mind - you
will get to the top in the end - enjoy it while you can.
My technique is to set a sustainable effort level - usually about 220-250 watts and enjoy the scenery; the top of the hill arrives 10-20 minutes later...
"There are no such things as hills - just slow and fast flat bits..."
