So for 1 workyear, if I attempt just that 1 IPPT, that also count as 1 low key ah?
No.
low key = 6 days
high key = 7 days
for myself i had 3 low key ICT each with 6 days. So basically if u add just 1 more day to each of this low key ICT, it becomes high key since 6+1 = 7 days.
1 ippt session you take in a FCC, considered as half day. So for example you take 2 ippt FCC sessions in 2 years, that will be half day + half day = 1 day. The computer system will add that 1 day to your low key cycle that you took previously (if u had taken). So for my case, it adds to my low key ICTs, thus i MR earlier. 50 percent of my reservist unit also MR same time. We all completed 3 low key + 5 high key and they MR us.
We are lucky that our low key is in the beginning of our reservist cycle. Our ICT roadmap started with 3 low key and last 7 cycle is high keys.
Bottom line is, all this calculation is done by the computer system, there is some algorithm that they will record all your IPPT FCC sessions, your ICT cohesion days etc. and they will tabulate it up against all your ICT. So for me, though only 5 high keys was done, my IPPT sessions get added to my low key sessions lo so most of us fufilled that 10 years ORNS requirements.
And dont take IPPT during an ICT, as that wont be counted as an extra half day as you are using the inclusive ICT days already. Take IPPT outside of ICT in a FCC, that what makes it count.
