Only counting tournament ("basho") wins ("Yusho") as a Yokozuna, for both men, will Hoshoryu win more than Kirishima?

If they win tournaments as an Ozeki, none of those count.

This should roughly translate to "Will Hoshoryu both become a Yokozuna and have a better run at it than Kirishima?"

Resolves Yes as soon as Kirishima is retired and Hoshoryu has more wins as Yokozuna.

Resolves No as soon as Hoshoryu retires with equal or fewer wins as Yokozuna than Kirishima.
