Max Zs Permitted by BS7671 value

Hi All, Thank you for welcoming to this forums I just want to clarify that the Value I need to enter 100% or 80% in the last column "Maximum Zs Permitted by BS7671" is it 80% from the table 41.3 from 18th Edition Regs - Page 62 or the value from Pocket Guide 18 Thank you Loges
