SCs inability with tomatoes

The main tomato I use for cooking is Alicante. It performs really well every year, doesn't suffer from greenback and is easy to skin. This year I've had a bad dose of tomato leaf mould or the yield would have been exceptional. I do have 33 plants in total, 22 grafted. From 9 alicante plants I've had 21kg so far. 2 Roma plum tomatoes still have lots of fruit to come and so far I've had 4.9kg off them.gardeners delight 8.8kg off 4 plants and 6.6kg from 3 galina. A lot of the plants will be dead before the end of September and a few could be pulled up now. My grandson loves the gardeners delight and galina.
I grew black russian once but wasn't impressed.

Results from 2021 Columns a bit jumbled but 'kg.' column is the total of all plants. g.d. is gardeners delight. Probably they were all grafted.
   

The total at end of August in 2021 was 39kg while the total currently this year is 62kg but there is no way I'll end up anywhere near 109kg this year with the state they are in.
