Is it just me, or did PD miscalculate?

[rojovo74]

I grabbed the Ford Focus ST '06 to use in the National B FF Challenge. The PP limit is 550 or less. I have the car maxed out power-wise, and it is still a bit short of 550. The in-game total is showing 528. but when I added everything up on a calculator, I got a total of 527, so this tells me that PD miscalculated on something total, since I came up with a different number. I'll add that I have yet to do an oil change.

My guess is that as the pp is only shown as a whole number, that the values have all been rounded up and that this is why there is a discrepancy between the two figures.

Either that or the total truely is worth more than the sum of its parts.

How do you calculate PP with a calculator?

How do you calculate PP with a calculator?

Starting with the stock PP, you simply add the PP gained with each part you add...if a car has a stock PP of say, 325, and you add the stage 3 engine tuning, the PP might go up to 340. simply add 15 to the 325 to get 340 - do this for each part you add (each power/weight reduction part added causes the PP to increase).

Oh okay. Well, PP is not showing decimal values so that's probably why you get a different result.

Edit: I was hoping that you had cracked the formula to calculate PP

@Thorin Cain would be right then, because as you add parts and watch hp, the calculation changes and you have more hp than expected by your calculator method. The pp would then reflect the extra gain compared to a flat rate increase.

The PP will always be shown as a whole number. Like I said, each part makes the PP go up. Ex. My Focus has a stock PP of 411...I added stage 3 weight reduction, carbon hood, window weight reduction, stage 3 engine tuning, intake tuning, stage 3 turbo, sports computer, isometric exhaust manifold, sports catalytic converter, and racing exhaust...adding the parts bumps the car up to 528 PP. And yes, the HP goes up as well..from 214 to 451 lol.

Yes, it's shown as a whole number but it's calculated with decimales. If you add five parts that each raise the PP value by 2.2, the calculator gives you 10 (5*2) while the games gives you 11 (5*2.2).

How do you know it's calculated with decimals? If you round off the numbers, then yeah, you get 10...5x2.2 is 11 on a calculator.

It would seem likely that decimals are taken into account (with both power and PP), as sometimes you can make a reduction of 0.1% of power limiter and drop 1PP, while the bhp and torque are "unaffected".

But if you don't see the decimals you can't input them in the calculator. That's why you'll have to input 2 when the actual value is 2.2.

It has to be a decimal value, there's no way the formula works with only integers.

Could be would be a better way to say it, and the formula probably has at least 4 parts to it so this idea with using a calculator would be difficult to do without knowing what PD's conversion rates are.

The pp has to be calculated in-game with decimal places. As @Lewis_Hamilton_ said, You can lower your power limiter and lose 1pp but not lose any power and vice-versa.
Think about it, if you need to use your power limiter to reduce your pp for an event, you notice that you will drop a lot more power than the resulting drop in pp. For instance you may need to loose 40 BHP to drop 10pp. Which in this example means that each BHP is worth 0.25% of 1pp. So if you add a part that gives an extra 100BHP the pp increase will be 25pp and if you add a part that gives you 5BHP your pp increase would be 1.25pp. Hope this helps.

Also, a partial explanation for the 40hp for 10pp example is that there is now more torque in the car causing the amount of hp removed by the limiter to be greater than an alternative.

Look at carbon hood and window weight reduction. I noticed that sometimes the description will show each costing 1 pp, but when both are installed only 1 pp total shows up, not 2 pp. Or a similar situation, window and hood both show zero pp gain, but when both installed, 1 pp total shows up.

For experimentation, I bought the Toyota MR2 GT-S '97...did the exact same thing as I did with the Focus, and I got the same results. However, the discrepancy with the MR2 is 2 (total on calc shows 531, while in-game shows 533, while the Focus is only 1 (on calc shows 527, in-game shows 528). This tells me that the discrepancy (if any), will vary from car to car.

This is hardly a surprise. You can try this on as many cars as you like and spend as much of your credits as it takes and you will probably find every car in the game is the same! And only in a very small amount of cases will it ever be less pp than you calculate, but this is another discussion all together.
But back to your original post...

Do you actually believe that PD miscalculated an equation that they formed themselves to use the weight, power, weight distribution, length, width, height, wheel size and who knows what else to calculate a cars pp? And that using a calculator to add up a few whole numbers is more accurate?

While you thonk about those questions let me answer the question in your thread name. Yes, it's just you. PD did not miscalculate! They just have all the facts and you only have what they have shown you.Your calculations will only be of any use to you as a guide to get you close to the pp you want to achieve due to pp only being displayed as a whole number and the actual values that PD's model uses obviously containing decimals.
