The charts are more to visually graph how blood levels look and I use it mostly for testing purposes and visually get a picture of how blood levels look with different inputs.
In reality, you want to go by the actual half life of whatever ester attached to whatever compound you use.
So using you 3 compounds as an example:
EQ(Undecylenate ester): has a half life of 14.5 to 16 days (couldn't find accurate info and never ran it myself.)
Enanthate ester: has 10.5 days half life.
Cypionate ester: Has a half life of 8.5 days (fuck me, come to correct me tankman, we both know i always get cyp wrong....)
And recommended waiting time for bleed down is double the half life, starting from last injection.
So your levels will bleed down similar to this, (to reach levels where you can start recovering, you'll still have exogenous levels inside you...:
EQ: 30-32 days from last injection.
Enanthate: 20-21 days after last injection.
Test Cypionate: 17 days after last injection.
So this means you'll first stop EQ about 12(14) days before stopping Enanthate injections (recommendation is 14 days, cuz its easier to say 2 weeks)
You'll will keep injecting Enanthate during these 12 days and then stop, you wait another 20 days for levels to bleed down (to essentially have all compounds/levels end at the same time)
You'll keep injecting cyp for 1-2 more injections after you stop Enanthate.
Then you wait another 16-18 days to start PCT.
These are overlapping and the whole tapering down to reach PCT should take roughly a month.
Hope this gives a better understanding of half lifes, esters and PCT
