Here it’s done with reduction of the offers to their semantic type:
as you can see the difference is not that much. example, lai dai goes from 275 to 236 semantic offers, and CN goes from 332 to 319
Of course I may remove the resource wars corporation (produce only 2 semantic types) and then remove the common types. (the 5*5=25 implants)
edit : added recursive calls. Seems like at most depth of three was needed. One line shows 125 offers for a group, but without any bigger offer list, while the next group has bigger corp, so that likely means I have a bug.
