At this point he made some very definite decisions on the direction his research should take, going back at looking at the original assumptions underlying his mathematical model and trying to introduce more realistic assumptions.
Sa puntong ito siya ginawa ng ilang napaka-tiyak na desisyon sa direksyon ng kanyang mga pananaliksik ay dapat kumuha, balik sa pagtingin sa orihinal na assumptions batayan ng kanyang matematiko modelo at sinusubukan na kitang ipakilala more talagang assumptions.
