I noticed that my chances of inadvertently slowing down go

Not a good practice - and, BTW, a technique designed to detect
a 10 knot drop in airspeed suggests acceptance of an approach
speed target range that is not sufficiently precise for safety in
one direction or accurate landing in the other.

Trim for approach speed, monitor your airspeed and look out.
