Can you guess how I managed to fit 5 days into a small cabin case?

Hi everyone and world travel fans/enthusiasts
How is everyone doing today?
I'm feeling happy as I managed to figure out how to fit 5 days worth of essentials into a small (read EasyJet sized) cabin case with room to spare.

There are a few changes made from last time (I was in Rome) that have enabled me to fit 5 days (instead of 3 days) worth of essentials with no vacuum bags or other tricks.I used the same technique as last time (rolling your clothes instead of folding them and putting them on top of each other.If you're not sure what this is please see the video below) but there are still a few differences from how I packed last time.

In case you're wondering what trip this is for,well it's for the trip to Barcelona this summer.

If everything in the clothing/essentials department is the same (except 2 more days are added on),then how can I fit 5 days worth into a small cabin (or carry-on/hand luggage)?What are the differences this time?Can you my fellow readers,guess what I've done differently or how I've managed to do it (despite adding an iPad Air to the mix to email photos back home and 3 extra accessories)?
