Your PMC might be more correct than you think.
I tend to agree with this statement here. I wish the OP will report back and tell us about how his comeback went.
We tend to pamper ourselves little more when we are sick, which often result into eliciting freshness, at least this is what I noticed over years.
In fact as a coach, my main *fear* related to periods off training due to sickness isn't too loose fitness, but rather to elicit an undesired peak. But if such a peak doesn't interfere with the racing schedule, it ain't that bad neither.
All that being said, and not to criticize the op's choice or reaction, but to me, 4 days off bike during summer because of a cold seems like overreacting a bit (especially if quality of sleep isn't altered - by using Dristan or the like for instance). Some shorter rides done a low level (L2) for instance wouldn't hurt, as long as the discipline to not ride intense is there. For a flu (with fever etc) it's another story.
As for manipulating TSB data, there's one good way of doing it, and it's by substituting a full day off by a recovery ride.

So for the cyclist with CTL hovering around 100 it drops ~2.4 points for every complete rest day and it takes a TSS 200 day to make CTL rise by the same amount
...
The good news is that it's the delta CTL vs TSS that matters in terms of how fast CTL drops or rises. So a complete rest day (TSS=0) makes your CTL drop by ~2.4%, but say your CTL is 50 and you do a very easy rest day ride that yields 30 TSS. Your delta is only 20 and the CTL drop is approximately half a point reminding us that even a light workout beats total rest in terms of supporting cumulative training load...
