Importance of quick cooling

[DRB]

I dont know if I've read this right ,but are you saying that you topped up to 23 lt which then gave you a reading of 1.012 before fermentation I think you might have diluted a bit much there,thats what it should be after fermented out.

Oh! no what have I done
I rushed down to see and check and thank goodness it was 1.052 a miss typing error.
Quite a strong ale I believe.
Just cleared all surface trub so it is on it's way

Belto,
If you have an SG of 1.052 in 23l of wort you got an efficiency of 82% from the ingredients you posted
Well done that should alleviate some of the worries you had
BTW at that gravity if it ferments down to 1.012 or so you'll have you 5% abv as well.
Well done, see it's not so hard really
