For the past few months, I have been working on the Speed and Turn Rate Formulae on Tribble. However, with all of the extra things that add speed and turn bonuses, it has turned into a calculator. Well, I have finished it and it is ready to share. Link is below.
Special Thanks goes to @adamkafei, for helping with early testing (and putting up with my constant messaging), and to @dabelgrave, for pointing me towards truncated values, which turned out to be quite important.
This calculator is as accurate as I could make it, while trying to keep it simple.
There are a few things that can throw off the accuracy of this calculator. The first being, anything that relies on a specific Power Level. The Power Levels displayed in game only show whole numbers. A displayed Engine Power of 80, could actually be anywhere between 80 to 80.99. It does not appear to apply to a displayed Engine Power of 125. While this does not appear to affect the result of the Turn Rate that much (if at all, I did not see any difference), the ship's Speed is affected more by it. This also affects Attack Pattern Omega, which derives it's boost from the ship's Engine Power; and also Auxliary to Dampers, which uses Auxiliary Power to determine its boost.
Also, I have found that some ships do not have the Impulse Modifier that they are reputed to have. Example 1: The Breen Heavy Raider does not have an Impulse Modifier of 0.21, but actually 0.15. Example 2: The Ferengi Na'Far has an Impulse Modifier of 0.22 and not 0.25. Example 3, the Light Cruiser, allegedly has an Impulse Modifier of 0.17, but it is actually 0.15. There are too many ships that I do not have access to, to verify every single one. I did post about it in the Bugs section of the official forums.
And finally, good old mystic math that Cryptic uses. There are variables used, that I am unsure of how Cryptic handles certain things. For example, some values are rounded up and some are rounded down. For example, Attack Pattern Omega is based on Engine Power; I have yet to have been able to figure out how exactly that bonus is derived.
Missing Information:
I do not have access to the Expedited Delivery Set or the Command Platforms Set. If you use either of these sets, and have the inclination, please let me know which Category boost they belong to. I have purposely created entry slots at the bottom of the calculator for the explicit purpose of testing new equipment or traits that may introduce new speed or turn bonuses.
Crafted, Reputation, and Mission Reward Engines
I have gone through all the Reputation, Crafted, and Mission Reward Engines, and derived their Speed and Turn Bonuses from the stats displayed and testing those engines on Tribble. There is a section in the calculator that will pull up the Engine type, Speed Mods, and Turn Mods.
