Trying to answer your question, I attached below two pictures showing the deflection of Albion Munich blade and mine, both type XVIIIb and having a required rigid blade.
Considering the size of both swords and taking into account their specifics, for example:
Thickness to width factor at the forte (width x thickness):
1.5 x 0.335 = 0.5025 (Munich)
1.975 x 0.26 = 0.5135 (mine, 1.975" being accurate width of my blade)
This factor practically being equal, it implies that to compensate for the thickness difference and keeping rigidity, mine needs a slower distal taper, as shown here ( thickness at the forte, mid blade and 4 inches from tip)
0,335 / 0,260 / 0.170 (Munich)
0.260 / 0.215 / 0.170 (mine)
A faster distal taper, or more distal taper for that matter, would have given me a thinner blade, therefore a less rigid blade and consequently, a lighter sword. Besides, that type of blade would have tended to be gradually more like a type XIIa or XIIIa.
The purpose of bringing up these numbers is just to show similarities in their parameters and their resulting qualities without getting too much in mathematics.
And then, just for the sake of argument, suppose I ground the blade some more and without drastically changing the overall quality of the sword, I removed an additional ounce (not very likely), will that make a big difference ?
The sword will still be a large sword.
