foolproof

Landed a bottle of ilfotec hc and not quite sure how to go about it as i'm normally a once shot man due to working limitations. If I do not want to make a working stock solution of 1+3 to then further dilute by 1 stock +7 water (gives 1 + 31) can I just go ahead and use the concentrate at 1 + 31 once I have an accurate means of measurement? I used to use this method with thick hc-110 concentrate and it was ok.
