I have accumulated DNA segment match information from ftDNA, GEDmatch, and MyHeritage. It is just recently that I've added MyHeritage DNA donors data, and I've found that the SNPs are two to four times the value of GEDmatch and ftDNA (when comparing the same donors). Does anyone know the reason for this substantial difference?

Below is a one example of many... (sorry, I don't know how to format the tables)

From GEDmatch.com:
Chr Start Location End Location cM SNPs
3 23,760,064 29,187,906 6.2 931
8 29,331,698 67,590,346 26.4 3,836

From ftDNA:
Chr Start Location End Location cM SNPs
3 24060170 29187906 7.05 856
8 29450700 68699024 25.84 3622

I have accumulated DNA segment match information from ftDNA, GEDmatch, and MyHeritage. It is just recently that I've added MyHeritage DNA donors data, and I've found that the total number of matching SNPs, for a segment, are two to four times the value of GEDmatch and ftDNA (when comparing the same donors). Does anyone know the reason for this substantial difference?
