Unfortunately there is no option to configure page size per User or per Custom view in TeamPulse. By default the page size is 100 elements for desktop and 15 elements for mobile devices. I have added a feature request in our Ideas & Feedback Portal
and you can give your vote up for it, so we can move it faster in development. I would like to encourage you to use our Idea & Feedback Portal because our client's feedback is important to us to make TeamPulse better and easier to use.
As a work around to your issue it is possible to change your default page sizes for the TeamPulse but it will affect all users that are using it. If you go to [Your TeamPulse Install Directory]\wwwroot\Scripts, open app.js file then find the pub.getPageSize function and change the values(see the attachment). Please, keep in mind that changing the default values in highly NOT recommended as it may affect your TeamPulse performance.
