I have an example from having compacted 200 moon boots.
Case 1: 56 grey block seed, 54 Pinball sproinger seed, 194 gems, 11 pinball sproinger, 31 garbage, 15 grey block, 2 MTSS-Yellow, 4 moon boots seed, MTSS - Red, 2 patchwork quilt.
Case 2: 21 garbage, 225 gems, 55 pinball sproinger seed, 58 grey block seed, 16 pinball sproinger, 19 grey block, 3 patchwork quilt, 2 tiny red skirt, MTSS - Aqua, and moon boots seed.
Case 3: 7 pinball sproinger, 52 grey block seed, 4 moon boots seed, 232 gems, 59 pinball sproinger seed, 4 patchwork quilt, 27 garbage, MTSS - Aqua, MTSS - Yellow, and 10 grey blocks.
I save the data I gathered from compacting moon boots. Without even calculating anything, you can clearly see that the easiest thing to get out of compacting items are the two seeds you spliced. It's around 1/4 chance to get one of the spliced seeds. Also, this is apparent to the other clothes I have mass produced to compact (e.g, fairy wand, growie hat, & fishnet stockings)
