Mathematically accurate % calculation for "over-score" scenario
I have G25=60 and H25=30, where a person was given 60 days to perform a task
and he ended up performing the task in 30 days. Thus he has "over-performed" and scores 150% for that task. If he completed the task in 60 days, I would have G25=60 and H25=60 and I would expect a calculated % of 100% performance. If he completed the task in 90 days, I would have G25=60 and H25=90 and I would expect a calculated % of 50% performance. I have tried using (G25/H25)-(H25/G25), whihc works fine for the top example and gives me 150%, but for all the other combinations it gives me wrong andswers, i.e. with G25=60 and H25=60 I get 0% and I should get 100%, and with G25=60 and H25=90 I get -83% and I shoud get 50%. Please help! |

Mathematically accurate % calculation for "over-score" scenari
Thanks RonaldoOneNil
I do however also need it to work correctly for any other single increments in the numbers, i.e. if I have G25=60 and H25=54, I expect an answer of 110% performance, and I get 190% with the formula above.

Mathematically accurate % calculation for "over-score" scenari
Hi Daryl S
Not quite: following my example, once I reach a situation of G25=60 and H25=120, I should hypothetically get an answer of 0%, since it has taken the member twice as long to achieve the result as defined by the terget (60) - but it actually returns 100%.
