I'm not trying to be mean or anything when I say this, but since it takes 3 strikes to get a pinnacle there should be no reason not to be able to complete bounties in 3 strikes, speed running or not. If you're having difficulty completing bounties by the end of the 3rd strike then it's plausible that the problem isn't the speed runners... here's what I mean; By now we know all the strikes by heart so we also know exactly where and when the enemies are gonna spawn. Try to be arriving to those locations around the same time as the front man to get your kills, because as they say "he who falls behind is left behind" Loadout accordingly! Most strikes are red bar ad heavy so equipping weapons with super low TTK or weapons specifically designed to kill multiple targets with one shot are a godsend. Trinity ghoul, jotunn, witherhoard, sweet business and weapons with dragonfly are perfect examples of ad clearing weapons that will guarantee you a decent kill count. My usual load out for strikes is vorpal auto rifle, trinity ghoul and temptations hook and I've yet to be at the bottom of any kill count per fire team.
