PC Server Grip Calculator

Discussion in 'Assetto Corsa' started by Tarros, Jul 27, 2014.

  1. hi m8
    I made two calculations in excel in order to find the optimal configuration for the server grip
    The calculations take into account the factor of randomness, tranfer rate, % grip for lap ect.
    requirements:
    Know the average lap time to calculate how much will be accumulated grip (enter in "seconds")
    Know the client on server to calclute max grip amount
    • the causal factor comes as causal calculated with a formula in excel to return the real start grip
    • is taken into account the transfer rate
    of course the file return the maximum values then as if the client had the most of the opportunity and most important a possible scenario on server.

    The purpose is to be able to set up a server with a credible grip transaction
    every yellow cells can be edited
    every session add a randomness factor as designed by kunos
    randomness is taken as 1=1% ; 30=30%
    added output for default preset grip as singlepalyer
    (Note for kunos scenario edit only client, minute or lap and average time on track)

    Hi, Thanks this a cool tool.
    Im not clear on one thing, in the picture I attached I cant work out why the final grip is .96

    if I started at .9 then did 1 laps with 10 clients then the grip should increase by 1% every lap right? as my lap for grip is set to 10.
    30 mins racing in practice at 88 secs a lap should be about 20 laps completed by each client which means approx. 20% increase in grip?. Yet the calculation says it only increases by 6% ie: .9 to .96
    I think you are compensating for people maybe not completing the full amount of laps for each client but that's still a big difference
    what am I missing?

    Regards

  4. so make new version
    introducing variable % of client run in a session
    introducing reference for groove to copy and paste to cfg.ini for server groove
    fixed format in % according to server display information in session
    this is a screen shoot of the new layout

    many thanks for feedback

    ok have a few more questions with picture I uploaded.

    10 clients and lap for grip =10 means each lap completed by the field will give a grip increase of 1%
    30 min practice@88mins a lap means 20 laps completed so that's a 20% increase in grip? yet yours only increases by 10%- I have set all clients run to 100%

    also why is your transfer rate not applying to the race?

    cheers

  7. Kunos said that transfer rate is applied to spread between start and end session, and
    start grip value is resetting to defined value for every session
    so : in your situation
    start grip =0.8 transfer rate=0.6
    end session practice =0.9
    qualify start=0.8+ (0.9-0.8)*0.6=0.86, qualify end session 0.96
    race start session=0.8+(0.96-0.86)*0.6=0.86

    Ops... you are right found a error in practice mode math count 0.5 of client now fixed ....
    @same link
    sorry

    Man this is confusing,i don't get your grip calculations according to what I have read the grip carries across from session to session

    so looking at your spreadsheet I have used .5 instead of .6 just for easier calculations

    start grip for practice is 80% finish grip is 100% that's fine
    Qualifying start grip should be 90% which is half the difference between the 80 and 100 which is also fine and finish grip is 100, so far so good but
    race start grip should therefore be half way between the 90% start grip of qualifying and 100% finish which works out to be 95% start grip for the race, not the 85% that your sheet calculates.

    The start grip of the race should not be less than the start grip of qualifying that does not make any sense.

    Regards

    Loving this calculator
     
    • Agree Agree x 1
  12. tested 1 private server seems that calculator v5 is the right tool!!!
    transfer applyng to previous session
    result
    1 server @magione evoragtc
    server configuration
    start grip93%
    1 client
    1 lap gain
    transfer rate 100%
    Practice 7
    qualify 10
    race 10

    on track
    practice 3 lap ont rack result : grip from 93% to 96%
    qualify 2 lap on tack result: grip from 96% to 98%
    race start @ 98%
    if calculator v4 was right server must report 95% grip
    more test more test more test...!
    @fixed on v5 format for value over 100%
