MSU:Water lightly and frequently during summer?

I live in Tennessee and was reading thru an article put out by the university here:

Below is the specific part of the article that i wish to discuss: basically-
I am trying to figure out which school of thought would be better for my lawn (which is Tall Fescue)?

"One irrigation philosophy is to water thoroughly
and infrequently in an effort to encourage
turfgrass plants to develop deep roots. The soil
is moistened to a depth of at least 6 inches and
the turf is not irrigated again until symptoms of
drought stress begin to appear. Many industry
professionals managing turfgrasses in loam soil
keep this philosophy in mind and set irrigation
systems to apply Ĺ inch (about 320 gallons per
1,000 square feet) of water no more than twice
each week. When thoroughly irrigating turfs
maintained on slopes or in heavy clay soils, it may
be necessary to activate sprinkler heads in each
zone several times to avoid runoff.

Another irrigation philosophy, based, in part, on
research conducted at Michigan State University,
is to irrigate lightly and often (e.g., 1/10 to 2/10
inch of water every other day) during the summer.
A goal is to meet the daily water requirement
of shallowly rooted turfgrasses while conserving
water by preventing runoff and the percolation of
water below the turfgrass root zone. Damage from
certain diseases and insects may be reduced when
water is applied by light, frequent rather than
deep, infrequent irrigation."
