Optimal Price For Swimming In Christchurch For Disabled Swimmers

The Christchurch City Council changed its fee structure for swimming pool admission as of October 1st, 2022. There are some important changes for disabled swimmers who have a Hāpai Access card.

While there is a 25% discount for annual pool membership, there is a 50% discount for casual entry fees. The later includes multi-visit pass. The question now is, how often do you need to swim per week before the annual membership becomes the cheaper option.

Annual Entry Costs based on number per weekly visits.

The graph above shows that you need to swim around 3.25 times on average per week before the annual membership becomes cheaper.

While I applaud the Christchurch City Council for increasing the discount for casual fees from 25% to 50%, I would have appreciated it even more if they had extended this discount to the annual membership. Active swimmers will be forced to give up their annual membership if they swim more than three times a week. Normally, discounts are setup so that the more you use a service, the higher the discount becomes.

No other discount category, such as Community Services Card or Super Gold Card, has this inconsistency.

For abled visitors with no discount or visitors with a 25% discount (Community Services Card or Super Gold Card), already visiting the pool more than twice a week justifies an annual pool membership:

 

It is unclear why the Christchurch City Council wants to make going to the pool for disabled swimmers more of a hassle than for others. Annual memberships is quick an easy. No need to constantly refresh the cards or pay every time at the counter.

It would be great if the CCC would make our live not only more affordable, but also easier.

Mechanical Keyboards Guide

A short list of the best mechanical keyboards.

Once you typed on a mechanical keyboard, you never want to go back to the stock rubber dome keyboards that come with most computers. And I am not even a gamer. I just spend a lot of time in front of computers. Even Logitech has entered the mechanical keyboard market aside from gaming with their MX Mechanical. It has become its own hobby, with enthusiast spending many hours on selecting, assembling, modifying keyboards. It is another rabbit hole. “How deep?” you ask? Just check out these YouTube Channels.

Instead of spending my own thousands of dollars, I decided I should rather eatable you to do it for me. So here we go, a list of my favourite keyboards. I have settled on the 75% form factor as the most suitable for me.

Bicycle Computer Mount For Bar End

This is a bicycle mount for a computer and a display unit of an ebike. It has 22mm and 32mm tubes to which computers can be mounted. The mount goes into the bar end of a steering wheel. This is paraticulary useful for recumbent bikes. The mount is designed for M5 nuts and bolts, but depending on the accuracy of your 3D printer you might need to use M4 bolts. You can download the 3D files over at GrabCAD.

Here is a technical drawing of the design:
