Current sources describe rounding, as currently practiced in virtually identical terms.  The Derbyshire TM Org website advertises rounding as part of residence courses, describing it as follows: For new meditators becoming established in their practice, a residence course - with longer programmes of meditation, pranayama and yoga asanas (rounding) - is a first step towards deepening experience of the transcendent. [emphasis added]  A 2008 advert for a TM retreat on the Isle of Wight contains a schedule: Three rounds – this comprises; 15 minutes yoga asanas, 5 minutes pranayama, 20 minutes meditation, 10 minutes, rest, repeated 3 times[Emphasis added] This particular series of retreats involved three "rounds" each morning, and one each afternoon.  That adds up to the same elements, and the same 50 minutes per "round" desribed in the older sources. It would appear that rounding hasn't changed at all in 30+ years.
