Looking for new focus farm method since DE gutted deception

[Skaleek]

Hey guys,
 

Looking for a few clever tenno that can tell me how I can max my focus rep in under an hour without an exp booster now. It used to take me 35-45m stealth farming ponaturi But DE has decided that if its not draco, it just shouldnt be viable. So please, if anyone has a really viable method of getting your full 100k focus in less than an hour, please enlighten me and be as detailed as possible, thanks.

Stealth running Ludi, Ceres with high duration high range Ivara, sleep arrows and covert lethality dagger.  Just keep all enemies in range slept so they don't become alerted to you killing things and keep the 500% multiplier going, sometimes hold off on big packs until a focus booster spawns then go to town.

This is one run, no boosters:
