It would be incorrect to say elders are noticeably quicker to get reinstated.
There are many intervening variables to how and why he might be though.
For example .....
I think it helps for the man to move out the congregation of where he was DFed.
The PO in my Hall was DFed for adultery, he was shagging young teenage girls on his businesses trips.
He moved to another town and another congregation where he was reinstated within 6 months.
Other variables could be how much financial contributions he made while being an elder and how much he participated in Assemblies, service work, pioneering, private bible studies he made and how many new members he brought into the organization.... etc ..
