I should think that, if the runway length is only marginal, a touch-and-go can be limited to effectively "going" - full power, in other words - as soon as the wheels have "touched" ground; instead of slowing down to taxi speed before going again, as I learned standard practice? As a student, the hardest point is short final and flare, or so at least it was for me.
BTW I seem to remember LHTL is a former military airbase with a longish hard runway so you must be talking about another aerodrome?
