If the entry fees is $1, then for $100 can swim twice a week, assuming 52 weeks in a year.........................

That is correct but it is also subject to weather too. If raining the pool will close so 52 weeks is not all weeks you get to swim. If you live in condo with swimming pool lagi best but every month the mainteanance is so high! I used to go to my uncle condo to swim as he pay never utilise. Later he sell liao. His condo very near where I live in HDB.
