Impact, Activity and Responsiveness

Actions however small and taking initiative are core OLIO values. We've been working on translating the amazing contribution of OLIOers into stats that you can relate to. Your impact screen is your data centre and here you can read about how we calculate the statistics...

Impact screen

How do you calculate “People shared with”?

This is the total number of OLIOers you’ve had a share with. A share is counted whenever it is confirmed that a share is taking place in the messaging thread between two users for a particular listing.

How do you calculate “Water saved”?

Based on data from a WRAP report  “The water and carbon footprint of household food and drink waste in the UK”, the average food listing requires 418 litres of water (based on an average listing weighing 560g, which is calculated via sampling analysis).

Food Waste Hero listings require an estimated 672 litres of water (based on an average listing weighing 900g, which is again calculated via sampling analysis).

How do you calculate “Meals saved”?

The average food listing has been estimated to contain 1.33 meal equivalents, based on 0.42 kg of food per meal equivalent, and 0.56kg of food per listing.

Food Waste Hero listings have been estimated to contain 2.14 meal equivalents, based on 0.42 kg of food per meal equivalent, and 0.9kg of food per listing.

What is "money saved" and how is it calculated?
If you have collected food from another user, you will see the value of the money you have saved on your Impact page, which you can access via the mobile app's sidebar. Currently, this applies to UK, Jersey & Guernesey users only. 

Money saved is based on food collections only. It is calculated by analysing the value of a representative sample of 1000 food listings, and from that calculating the value of an average pickup. We haven't yet analysed the value of non-food listings, but hope to soon. 

What is "responsiveness" and how is it calculated?
Responsiveness data is only shown for users who have added at least 1 listing. 
It is calculated every 2 hours to avoid sudden changes as follows:
  • Replies to x % of requests - this is based on replies to the last 11 (or less) requests received
  • Typically replies in x hours - this is calculated as the median of time to respond for the last 11 (or less) requests received

Are non-food listings included in water saved?

No. Non-food listings vary considerably in size and material, so we are not able to provide average water saved at present.

Does “Listings offered” and “Listings received” contain both food and non-food?

Yes.  However  it does not include 'Wanted' listings. 

Why don’t I see ‘Impact’ data on my profile?

We’re rolling this feature out shortly so if you don’t see it now you should within a few weeks.
