In the Thoroughbred industry when one is evaluating a standard pedigree page, not just a 5 generation pedigree as you linked to, be it for purchase or planning a matting we look at two things; The top of the pedigree, the Top line, the sire of the subject horse. The sire line the strength of which is mainly taken from the very top line, the sire of the subject horse (1st generation), sire’s sire (2nd gen) , grand sire (3rd gen) etc. The dams do not hold the same relevance or near the same strength as the bottom line. If planning a breeding we will take it into consideration depending on the method, inbreeding, line breeding, etc. On a standard pedigree page there are only 3 generations. After that comes the sire blurb, his year of birth, race record and list of his most successful progeny if any. Or some other fill.
The bottom line comes next. The dam of the subject horse and it is looked at more closely, broadly on both sides. Her sire line, called the broodmare sire and more importantly her maternal line the very bottom on a multi-cross. La Troienne, 1926-54, 7 starts, placed twice is considered a “Blue Hen” mare, or a modern day foundation mare. La Troienne can be found in many pedigrees in many places, but the most valued is if the subject filly/mare is a direct descendent through her very bottom line. In others words her great, great, great, etc, grand mother.
A pedigree page will have the 1st dam, her race record, number of foals, number of foals that raced, number of foals that won. If she only had winners it list the ones with the most earnings and or stakes placed. Along with their sire.
If she produced stakes winners they will always be on the page, type of stakes and money earned. If one of her daughters is a producing mare it will say, producer. If she is the dam of a stakes winner it will list their name and race record
The same for the 2nd dam, 3rd dam, etc. The number of which is limited to the size catalogue page. A prolific producing 1st dam family is considered a “strong” 1st dam and may take up the entire page.
So, what does this all mean to the OP question. 1st now that there is a link to the “subject horse” Move ON, disregard the value of my previous post. It is irrelevant and a foot note as to the value. Either in dollars or in blood of the mare. IMO based on just names and race records of her bottom, unless she has produced some good race horses, at least a stakes winner or stakes place or a half sister to some good to very good race horses and or producers she has little to no value as a broodmare to produce race horses. At 14 she should have been able to produce a couple of significance race horses by now. Her top line Gold Meridian was an OK race horse and moderate sire and not a broodmare sire of any significance.
Sorry to be so long winded but I felt it necessary because I read too many posts picking apart Thoroughbred 5 generation pedigrees only based on the names. And giving far too much credit to middle placed family, generations back. With Thoroughbred race horse buyers and breeders the first 3 generations carry 99% of the weight. Everything else is frosting. The sire is a given, there are plenty of top sires that were bred to what turned out to be non producing mares and or families. The real strength of a pedigree is the bottom. The dam side. I completely understand why students of pedigree like to pick it apart. It makes for good conversation and fun. But anything past the 3rd generation adds little value or strength. Of course all of this is IMO. And many others also.
