That pair of plants gave me 2.6 ounces of bud combined, and just shy of an ounce of trim.
Nothing stellar, but I cycle quick. I keep my veg periods short to keep pace with the frequency in which I take clones, and I don't utilize techniques like scrog and lollipopping. If I kept them in veg another month, I could easily see 2 ounces per plant I'd think. In contrast, there are guys on Reddit that veg their plants for longer than my entire grow takes, and they regularly pull 6+ ounces per. I'm not a fan of growing like that though. I think it's too much of a liability, at least for me. If the power goes out for a day or two five months in, or if I want to go away and have someone tend to them for a week or more... there's just too much that could go wrong. I'd hate to waste months' worth of electricity and nutrients only to have the plant go belly up. Cycling lots of smaller plants in a similar timeframe is my preferred method.
