Yes, but there are none (tactics) for 195% core output, except suiciding your core when you want a quick remake due to imbalanced teams. I do not find that a reasonable cause to leave core as it is right now.
As a matter of fact, correct me if I'm wrong, but if you're being boosted upon how will 150% core help you, except it will take longer for you to accelerate your engines (you will not be able to press the [q] button down, and that is at least 2-3 times faster then just spam pressing it) and your core collapsing will cause problems with all consoles. By that time (if YOU are being boosted upon, you will already have enough energy reserves to play around with), so putting yourself into an EMERGENCY core state, will put YOU into disadvantage compared to ME fast boosting over to you, when i only have core output at 120%, why would someone who boosted on you let you go, even if you gain your speed, a good power manager will do the same, and seeing you will not defend as for now, he'll reduce his shields to a suitable value to just be able to protect if u decide to fight after all, or just erase them to a very low value if your shields will be offline. Thus after a 1 minute chase, you will start experiencing problems with your core, and you will be pushed off console, which will make your and your nav reactions dull, not to mention you wouldn't be able to put up a fight anytime soon, because of weapons blackouts, which would make me, having my stable output of 120% into a position of having slightly less energy then you but stable enough, more over after 3-4 minutes of chase you will have your core so low, that you will not only be in grave state, but also will be forced to put your core output back to a stable value, while i will still keep it on 120% maybe will push it to 125% seeing i am almost out of energy. So in 2 more minuts i will outpower you with my output and my core will still be stable, maybe short problems with blackouts.
Not only you will be out of power before me, but you will also have you, your weapons and your navigation at 30-50% efficiency
Now reading my actions, which i shouldn't really post to public, how do you find your methods of putting 150% core in that situation more suitable?
--------
Now if you finally agree to me at that point, immagine if instead 150% of core putput, which brings you COMPLETELY NO BENEFITS in this situation at all, you would be able to put it to 200%, but decaying will be same as if it was 150% (I'm repeating myself, but still, I am not saying we should reduce decay rate, just cap them at 150%, thus 150-200% would all have same decay speed), compared to me with my 120% output, you will definitely outpower me, but your defensive and offensive functions will be f**ked up by low stability, so you pay the price of weapons and nav offline but gain more energy then i do even in a long term fight, cause, you know, if i'm the one chasing, i wouldn't push my core to 200% unless needed, because i do not want to lose my functionality. Thus you will be able to escape me but the price will be not being able to fight back, reasonable, worth giving it a go.
At the moment there are only 2 situations that make a good power manager, not a team core destroyer to use 150% output:
1. You are out of energy and getting attacked by a dessy with quantum leach, you really need a high output of maybe 180 to get enough energy to boost and then raise your weapons to be able to escape.
2. You had a long fight with your enemy, but your energy pool for both weapons and ship went down to a low value of ... lets say 5k, same goes for your enemy, so it'll be a good idea to put core to 150% and use that power to finish it off.

I've used my tactics to get away from a situations where our cruiser has 20k energy and 20% hull against hostile 80k energy, 90% hull, after my team put me in such a situation. And yes, that is all the fault of poor enemy power management, or lets say not poor, but not skilled highly enough. It's not that he drain those 80k chasing me in one instant, but after 5-15 mins of chase he had 20k and i had 14k (time flows fast when you play cc

, so i can't really say if those were 5 or 15 mins).
