I was just looking at that, and Ive figured out the formulas for a pretty exact answer. For these formulas use the low level in the range, and vr levels start at 51. So for the purpose of the formulas a 40-50 glyph is considered 40 and a vr 5-7 glyph is considered 55.

for 1-45 whites XP = 23L -10
for vr 1-10 whites XP = 46L - 1309

For greens multiply by 4, for blues multiply by 5, and for purples multiply by 6.

These formulae arent perfect but they are close.

And of course, these xp are for crafted runes made by another crafter.

thanks, but excel did the heavy lifting
