Your example is possibly within the range of variation between the different companies, but there are certainly some results that seem to me to be outright mistakes.
I imported an ftDNA result to MyHeritage, with one person I see a largest matching segment as 14.1cM on Chromosome 15 between 20004966 bp and 22852884 bp. The Rutgers page say this is 6cM for females and 2.4cM for males, with a few tenths difference between build 36 and 37.3.
Not only that, but MyHeritage says there are only 128 SNPs in that range that make up the match. This region is next to the start of the hatched region on the chromosome browser, which I suppose is the SNP-poor region and whether it has something to do with this or with comparing ftDNA with MyHeritage I don't know.
