Found a rounding mismatch between missile optimizer and Aurora.
Techs: INPE, 2.5 boost, .9 fuel, 4 warhead strength, 32 agility
A 0.53MSP engine with 500% boost will, in Aurora, have 1.32 EP and 6450 Fuel per EPH. Optimizer will report 1.33 power and 6499.29 Fuel per EPH. Optimizer also reports an elevated cost per missile.
Aurora is rounding engine power down (it is exactly 1.325 EP).
You can replicate by asking for an accuracy optimized size 1 warhead 1 missile with 1.7 mkm range.
Also, aurora appears to round 0.5 to 1 for agility, so you don't need to go to 0.51 when optimizing agility.
Thank you. It is another example of Aurora is consistently inconsistent in the choice of rounding.
So what you have confirmed is that engine power is again, 'rounded to even' at 2 decimal places. You can confirm this with your current tech:
A 0.55MSP engine with 500% boost in Aurora will shown to have 1.38 EP although 0.55x0.5x5 = 1.375
So 1.325 is rounded down to 1.32, while 1.375 is rounded up to 1.38.
There is a similiar rounding in the calculation from agility to MR. For a size 1 missile, 0.5 agility will be 10MR while 1.5 agility will be 12MR. The optimizer calculates the required agility to 4 decimal places and round up, so it is expected sometimes the agility shown in game is slightly larger than the minimum required.
