Modifications to Korte 3x3

i have run two consecutive volume cycles of Korte 3x3 program and it was great. The volume was very high but the percentages were not so high so i could train squat deads and bench 3 times/weeks whitout any problems. My tecnique and coordination also improved a lot.
Now i have to enter the intensification phase, but in the original version the volume is very very very low since the beginning of this phase (3x1@80%).
Anyone made some modifications or adaptaion to this phase?
Thanks a lot!
