If the culprit knew the train schedule so well, he'd do things the
safest and easiest way. Taking a train to Euston, then another to get
back to King's Cross so he could plant the bomb on the Picadilly line is
just too complicated.

Not really. Euston is the closest station to KX (2 min) at that time of
day, trains are spaced "2 to 4" minutes apart.

In practice, they're 2 minutes apart throughout the peak hours.

At Euston Square (*NOT* Euston) you have to go up a staircase, over a
bridge, and down another staircase to change trains. At King's Cross the
two directions are separated by an island platform.

If we knew the ACTUAL times the trains arrived at King's Cross, it would
solve the matter.
[...]
The trains start running from various points on the Circle so spacing
is more important than scheduling. The key is the "2 to 4 minutes"
apart.

You both appear to be assuming that trains 204 and 216 were targetted
and timing is essential. Much more likely is that two random trains on
that part of the Circle were targeted. They come along every couple of
minutes, after all. The bomb on train 204 exploded just before the point
where one third or so of the trains diverge; that on 216 shortly after
the point where 40% or so diverge. Provided that, on the westbound, you
avoid the visually distinctive Metropolitan Line trains, any train will
do.
