Multiple node saves required for many computed fields in one content type?

Hi, using version 6.x-1.0-beta3 on Drupal 6.15 and experiencing the same issue as this closed issue. I have a content type that calculates job costs and has 53 computed fields based on calculations from formatted decimal fields. There are many times when I have to save the node twice or three times in order for all the fields to calculate. I've thought about using Rules to perform a Save Node action when the content is created to try and avoid this, but would like to know the reason this might be occurring. Would anyone know what could be causing this, or where I could look to try to troubleshoot? Any tips would be greatly appreciated!
