HCL Domino Ideas Portal
Welcome to the #dominoforever Product Ideas Forum! The place where you can submit product ideas and enhancement request. We encourage you to participate by voting on, commenting on, and creating new ideas. All new ideas will be evaluated by HCL Product Management & Engineering teams, and the next steps will be communicated. While not all submitted ideas will be executed upon, community feedback will play a key role in influencing which ideas are and when they will be implemented.

I think an estimation tool is not the way to go as this would be as precise as rolling dice.
A better solution would be a monitoring tool that monitors either all or a specific database's transaction behaviour. Basically it should write statistics records for every transaction written to the translog files (preferable in a flat file, maybe as CSV) so you can apply the tool of your choice to actual behaviour data.
