I am a Spanish R1a, How am I going to share more with Leto just because he is R1a too than with any Spanish or Portuguese???
I have hundreds of matches (just with 12 markers) from Baltics, Russia, Poland, Czechia (practically all my Ydna matches are Baltics/Germanics/Slavics/Scandos) after doing my BIG Y, but not a single one of them appears as "relative" to me because we share a significant (or even minimally appreciable) part of of our genome on the whole.
Maybe even Leto is Ydna match of me in FTDNA, I have many Belarusians too.

You’re confusing many things. You share with your father 100% of your Y DNA. Depending on the haplogroup and subclade you generally share 90% of Y chromosome with members of your haplogroup, but like I said it’s relative and could change depending of the haplogroup. You share plenty of SNP’s but not only share SNP’s, it includes genetic material aswell. R1a has 102 defining mutations. ChatGPT explains it well.
FTDNA checks your STR’s, not your SNP’s. It’s for finding very recent people with your haplogroup. Nowadays it’s SNP’s that are in use. 23&Me only use Autosomal chromosomes and the X chromosome, not Y. I will attach below from their website the disclaimer. If they included the Y chromosome everyone would have thousands of second or third cousins which would make the idea pointless, and it’s way more expensive to include Y Dna as well, it’s a commercial company after all.

1556 SNPs in total, most of them shared with different haplogroups, things are not so simple as if I have CTS10168 positive all men that have CTS10168 have my haplogroup, in fact most of the individuals positive for most of the SNPs I am positive have not even have R1a.
Similar to CTS10168 (a random one among my positive SNPS) most of my positive SNPs, just some of them determine my haplogroup, and some few of the specifically my final clade.
All this specimens share that SNPs with me, and are not necessarily R1a...do you understand?

To have an idea, the SNPs to determine my R1a-Z280 starts is the 1500 of these 1556...a simple R1a is in the 727th...
