    Brew day went ok but I only got 17l instead of 21l this has happened before, anyway I was sat thinking about this loss, how much is lost to grain after mashing I have never calculated this or factored it in it's the only part of my brewing I can put this loss down to

    I found brewers friend calculations are pretty spot on. I went from 19 to 13 litre, welcome to the party pal!

    You've already got a rough answer its the difference between what you should have had and what you have got about 4 ltrs

    What is you actual OG compared to your target OG? You may have less wort but it might be overstrength. For example if you have 17 litres with OG1056 and the target OG was 1050 then calculate 17 X 56/50 which comes to 19.04 so you can add two litres of boiled and cooled water to top it up to 19 litres for example.

    found some of it losses to trub and chiller were set at zero now set at 2.0, grain apsorption is set at 0.60l per kilo does this need to higher

    I have my grain absorption set at 1 litre per kilo of grain not given me any problems. only problem I've had was boil off rate.

    Grain absorption is roughly a one to one ratio,take into account your deadspace loss which includes trub and liquid below your valve outlet and then if you're using a plate chillier you need to account for this plus hoses attached.
    Fill your boiler/brew kettle to full volume and boil with just water and after an hour cool and drain as normal and drain to your FV and measure your losses.This will give you boil off/deadspace and chiller loss.
    With this done you've just calibrated your equipment and add it to your recipe calculator and then allow for extra grain you'll need to add for your losses and get your target FV level.
