Explanation:
The decision of Raphael about pool versus bike time is totally a "how-much decision". It is clear that pool time and bike time can both reduce the time for race. However, the efficiency of pool time is high currently, and hence there is much sense in trying to spend more time in the pool and less on bike. This however makes no sense that all the time is spent in the pool and no time biking. Raphael only intends to alter the number of hours spend on each activity at the margin.
