What do you observe if you wait between touching foo.r and touching foo.p?

$ rm foo.*; touch foo.p; sleep 2; touch foo.r
$ make -f makefile1
$? = foo.r FORCE
touch foo.p ; touch foo.q
$
$ rm foo.*; touch foo.p; sleep 2; touch foo.r
$ make -f makefile2
$? = foo.r FORCE
touch foo.p ; touch foo.q
$
$
$ rm foo.*; touch foo.r; sleep 2; touch foo.p
$ make -f makefile1
$? = FORCE
touch foo.p ; touch foo.q
$ rm foo.*; touch foo.r; sleep 2; touch foo.p
$ make -f makefile2
$? = FORCE
touch foo.p ; touch foo.q
