Hi there! Happy 2021!
I’m a 2019 sponsor and I can share how I increased my chance of getting the spot.
First of all, I upgraded my internet to be the faster option, then I connected my computers using Ethernet chord, since WiFi are slower with the usual router. Then I had two computers ready to make sure if there is technical glitch at one computer, the other one would still work. This turned out to be a great decision since I ended up only able to open the page with the back up computer.
I also downloaded the interest to sponsor 2018 form to practice typing up the infomation that they needed on the form. And had all the required documents ready in the most accessible folder.
I ended up submitting the form within 3min and was still able to access the form till the 6th min.
However, I agree that the 2019 method is not fair for people with barriers, as they may not be able to type or comprehend as fast.
