I do not care to get into a discussion on the accuracy of the figures listed by NER. That discussion has already been completed elsewhere. I am only listing an alternative to dynaglide for those like myself who are not a fan of the bright colors. You are free to choose whatever cordage you feel appropriate for yourself, as I do for myself.
FWIW, I measured a sample of both Dynaglide and Endura-12 as above and understand that the smaller sample size would lead to a potential larger degree of error compared to a larger sample. The purpose was to compare the two cords' weight, not to verify NER measurements. By my scale, both would weigh ~73g/100', close to what others have reported.
I have not counted the number of crossings per inch and doubt I will do so. Non-empirically they look the same. Sorry if this this is not satisfactory to you. I will beg your indulgence, as I have now been up for 26 hours having started a string of night shifts last night. Again, I do not wish to rehash a discussion that was had previously as it turned rather contentious.
