Shinshinto.
I cannot see what your papers say. I am assuming "Sukesada" or "Sukehira". They worked both in Soshu style and that of Oei Bizen. I enjoy Oei Bizen very much, so I often take a look at Yokoyama swords.
Point scores are just a 'helpful indicator'. 75 is very good.
Assuming 50% of blades failed shinsa (probably higher in this shinsa), then it is sort of a pyramid scale from 70pts for passing kanteisho to 80pts being a possible Juyo candidate. Some blades are marginally passed with scores in the 60s. The reasons can vary.
Just for convenience sake, conceptualize that of the 50 that pass out of a pool of 100: You have 4.5 with scores below 70; then 9 with 70pts, 8 with 71pts, 7 with 72 pts, 6 with 73pts, 5 with 74pts, 4 with 75pts, 3 with 76pts, 2 with 77pts, 1 with 78pts, and 0.5 with 80pts (yes, we skipped 79 because I've never seen a 79 score to date) that is a Yusho (NTHK equiv of Juyo).
If you approach it this way, then you could feel that the NTHK felt your sword was in the top 6 to top 10% of the ones they saw at the shinsa. This is very good. Remember the point score is just there as a rough indicator.
My own feelings were that the quality of swords submitted was lower than I'd seen before. However, the quality of the fittings submitted was much higher than I'd seen before. Quite a few published items, and some big names- though I do not think anything was felt to be Yushu level. The judges were extremely hard- but some great collections made it to the fittings table.
You should be happy with your results, though maybe you were expecting Koto Bizen results. Do not sneeze at Yokoyama. It is not Bungo. We save those for Milt.
