Sweet Gem Berry, Greenhouse loop

Sweet Gem Berry, Greenhouse loop
Assume you have level 10 in farming. That means 46% of all harvest will be normal quality.
Expected value of Seed maker is 1.9502 seeds.
46*1.9502 = 89.7092(%)
That means if you put all normal quality SGB of the harvest into seed maker, on average, it'll return ~90% of the seeds you planted > You need to sacrifice some Silver star SGB
1 - 89.7092% = 10.2908%
10.2908%/1.9502 = 5.2767......%
You need to convert additional ~6% of all harvest to sustain the loop
At farming level 10, 33% of all harvest is silver
5.27679......% * 100 / 33 = 15.9902......%

Now the profit of the said loop, where we sacrifice 100% of all normal SGB and 16% of all silver SGB

Profit from all normal SGB (per plant): 0
Profit from all silver SGB (per plant): 3750*33%*84% = 1039.6213g/24d
Profit from all gold SGB (per plant): 4500*21% = 945g/24d
Total 1984.6212g/24d per plant = 82.69g/d per plant

Compare to the Ancient Fruit
Since it is Fruit you can benefit from Tiller
Profit from all normal AF: 605*46% = 278.30g/7d
Profit from all silver AF: 756*33% = 249.48/7d
Profit from all gold AF: 907*21% = 190.47/7d
Total 718.25g/7d = 102.60g/d per plant
