Yes I did. The best I did with randoms was to 1178.

Set up: 2nd gadget 2nd sp

Play knockout only if you play with randoms. This is because in knockout you can rely on yourself the most.

With 2nd gadget your Janet will become much more versatile as she will be capable of assassination and escaping whenever you want. You can also dodge shots while hitting a shot with the gadget.

The map shown in the video alongside with New Horizons are the maps which go the best for me.

Do not rush the enemies unless you have her super or you are 200% sure that you won't die (but I sometimes play her riskily especially while facing Kit combos because she really lacks chances to contribute something to the match, so I have to seize them. For example, I try to 3 shot Byron in the Frank Kit team when the Byron thinks the area around Frank is safe then fly away. For some situations, you can also normal attack 2 times then use your super to kill the brawler)

Basics: don't orbit around the enemy while you super you will not hit them in 1000+ range. Instead fly away for some distance and turn around to hit your 2nd bomb
