That's pretty bad... When calculating the efficiency, transitional effects and non-ideality of parts are critical. And what does the author choose? A generic mosfet, unnamed diode, constant duty cycle.. this is not realistic at all. And the selection of parts seems just random, especially given low output power (0.1W), no design will use it. A MOSFET for 5V circuit. 1KHz switching frequency (!). Fixed duty cycle and voltage regulation via inductance changes (!!). Huge inductors (0.3H!), because of very low frequency. All this blog post shows is that author can put parts into simulator. Very little relation to real world.
