The thing you need to understand, Uso Tasuki, is that the Star Army Roleplay is currently plagued by ships whom have utterly unrealistic traveling speeds - something even you have ridiculed at some point. The introduction of the SRP system allowed us to tweak engines so that they would become more cost effective and some of us have taken the opportunity to contribute to that.
The current speeds in the SARP very often defeat the purpose of the actual roleplay that is in fact being implemented. They don't match the use we should and can make of them - this isn't a case of people not being to accept being in a futuristic setting with high technology, but rather that big numbers have been put in places and that we simply can't respect them due to how ludicrously logic-defying they are.
I'll use a metaphor and present to you cars. Cars are generally used for specific purposes in mind. The domestic car, usually used for transit from one's home in downtown to more bustling traffic areas in the city proper usually goes at 110-120kph top, though it could reach around 200kph if it was pushed. In the same manner, Formula One racing cars typically range more around the 300kph and can probably be pushed higher to the 400+kph.
However, following the same metaphor, SARP vessels such as the ones produced by KFY go up to 2800kph! Even if they are made for - lt's say - racing... they are still ludicrously too fast! There's no way they can make proper turns on the Formula One race tracks going at that speed! So, even if KFY makes super-powerful engines, their cost and effectiveness are actually not needed all that often unless they actually have to travel in a straight line for a very long time without the use of fold drive systems - which are better made for such activities.
You, in turn, have been trying to make ships that go to 3500kph, simply because you feel you can, because there is precedent, and because you wish your submissions to be hot and totally miss the point that even if you do get that kind of speed out, you won't be able to make proper use of them... and so, your engine systems on the starships proper end up being a huge waste of materials.
Pardon the expression, but haste makes waste. Literally, here. And people keep doing it.
I tried making a detailed starship battle with the Miharu and considering how distances were being spanned and I quickly noticed how needlessly powerful some aspects of engine drive systems were in the SARP, which leaves people like Vesper and Lady Xerena to look at us, point and say "You suck!" And that might be more right than we'd like to admit!
So, with the SRP system being up, I decided that we needed to work to lower our top speeds. Most GMs I talked to agreed. Wes implemented a economic way to achieve that. Now, very fast means around 20 000c. Good fold speeds are below 1 ly/m (with .4 being fairly good).
With your drive system, you either have the choice of cooperating and participating to that endeavor, thus helping technology as a whole in the SARP and setting yourself as a good example... or keeping going for stuff OVER9000 and continue getting slapped by a wet trout.
Your choice. Help the SARP get better or help it stagnate.
