Formula for calculating Neanderthal Percentage?

[MFWare]

You must take Neanderthal ancestry with a grain of salt--maybe a teaspoon of salt. I have too assessments of my Neanderthal ancestry. 23andMe has me at 2%. Geno 2.0 has me at 2.8%--40% higher than the 23andMe result.

If someone has a formula, then the result has three possibilities: 1) it agrees with 23andMe; 2) it agrees with Geno 2.0; 3) it agrees with neither. In either case, you have a disagreement with at least commercial assessment. How do you arbitrate the disagreement?

Hah, that's what I'm trying to avoid! Seems like a shame to pay 99 bucks when I can tease of the info from the raw data.

Take the 23&Me test...only $99 Ha

Does anyone know the formula for calculating an individual's Neanderthal percentage?

I tried to run my raw data through Interpretome and it didn't take the FTDNA file. So I ran it through Promethease and out of the 42 SNPs I got 22 (see below), that seems like more than the average of 7 to 10 SNPs for Europeans, but it doesn't give me the %. So given my result, how do I calculate the estimated percentage of Neanderthal DNA I have?
