I think the point when trying to improve the efficiency, is to have minimal current at the zener and maximum current at the load resistor! Also we have to pay attention to Rs so that the zener can work within it's current parameters!!!
I'm sorry that I can't do any more calcs at the moment for this problem because I have 2 another reports to send to 2 other classes teachers, one for tomorrow and another for tuesday!
As you might know, we have very limited time! I'm sorry! But I really appreciate your help... You really have been an important help in my tasks, this and last year!
The other 2 classes name's are "Electrical motors/engines" where we learn the basics of transformers, losses, power efficiency, iron losses, copper losses, Foucault losses and so on and also inductive motors/engines and that kind of stuff (I don't really like this stuff). The other class is Industrial Automation & Robotics where we learn the basics of PLC's (Omron using CX One software and Siemes S7-200 using Step 7 software) and also learn the basics of Motoman robot! I think I don't like this one either- but is better than Electrical engines/motors!
