Modern over rates are so slow. What's the rule about this and is the rule good enough?
I have this pdf file downloaded, from there
16.3 Minimum Over Rates
The minimum over rate to be achieved in Test Matches will be 15 overs per hour.
The actual over rate will be calculated at the end of the match by the umpires and will be the average rate which is achieved by the fielding team across both of the batting team's innings. In calculating the actual over rate for the match, allowances will be given as follows:
16.3.1 The time lost as a result of treatment given to a player by an authorised medical personnel on the field of play;
16.3.2 The time lost as a result of a player being required to leave the field as a result of a serious injury;
16.3.3 The time taken for all third umpire referrals and consultations and any umpire or player reviews;
16.3.4 The time lost as a result of time wasting by the batting side; and
6.3.5 The time lost due to all other circumstances that are beyond the control of the fielding side.
16.3.6 2 minutes per wicket taken, provided that such wicket results in the subsequent batsmen immediately commencing his innings. For the avoidance of any doubt, no time allowance will be given for the final wicket of an innings or where a wicket falls immediately prior to any interval;
16.3.7 4 minutes per drinks break taken (one per session). In the event of any time allowances being granted to the fielding team under 16.3.4 above (time wasting by batting team), then such time shall be deducted from the allowances granted to such batting team in the determination of its over rate. If a side is bowled out in 31/2 hours or less (taking into account all of the time allowances set out above) in any particular innings, no account will be taken of the actual over rate in that innings when calculating the actual over rate at the end of the match.
