WorkLog Pro - hard coded time increments.

[Jason Adams]

Is is possible to only allow users of WorkLog Pro to  log log work in 15m increments? .25h or 15m being the lowest and 10h being the highest with steps every .25h.

1.5h being a proper entry but 1.52 being rejected or warned on.

I want to add more details to Jason's answer,

You can write a worklog verification script using scripting feature of WorklogPRO, and you can do any kind of verification easily. 

The other part of your question is due to time tracking settings of your Jira instance (not WorklogPRO). If you set your "default unit" to "minutes" Jira will reject 1.52h but will accept 1.5h as worklog entry. Because it doesn't round to a whole minute. Since WorklogPRO delegates storage of worklog to Jira itself, the same worklog will be reject by WorklogPRO too. Either you need to use numbers that converts to whole minutes, or you can set "default unit" to "hour".
