I describe the situation better with screenshots
As you can see, the extra production given by the crawlers is the same whether you put them at 90% or 150%. Even if at % smaller, I have this problem in all normal universes in which I play
That's exactly the application of this feature - reducing power consumption by pumping T18. I'm not sure if it matters for advanced accounts, but we have what we have 
Already discussed many times and asked to remove this limit, alas.
And a few words off-topic.
I have more than 20 years of experience in the game and OGame has always attracted me by the possibility of application programming. When creating the utility, I pursued the goal of creating a convenient version of the calculator, not overloaded and at the same time with complete input data, so that you can calculate the production of the Empire to your hearts content. I hope you will like what I have created. If someone wants to adapt the utility as a web version I don't mind
I also want to say a little bit about builds. Recently there have been more and more cases of false positives on builds of .NET applications in Visual Studio 2022, now I don't think the antivirus is complaining, but it is possible that it may happen again. Most likely it is related to the fact that Microsoft embeds a dotnet downloader into the application, which is considered by antiviruses as suspicious code. In any case, you can always build the utility from source, you only need VS2022 for that, the build should be done out of the box.
Enjoy
