@ Ocampo
You are most welcome.

The thrust drop is compensated by RAM RISE, however it is not enough in high bypass engines.
For initial high altitudes like FL300 there is a drop but not very significant. However for high altitudes like above FL350 this drop might be significant.
At low altitudes most of the work is done by the FAN, at high altitudes most of the work is done by the jet engine core.
