Windows 10: System Restore space

Much much space do you allow for system restore points. Is there a general rule. Like to hear your thoughts on this.

Free hard disk space reduce after system restore

I clear the log from EventVwr.msc but it did not recover much hard drive space. So i try clearing the retore point. Now my free hard drive space is about 34.4GB as compared to 26.6GB after my system restore.
Anyway before i did a system restore. I did create a system restore point manually from system restore. Will the system restore point account for the lost free hard drive space?

If your system is running ok now, you could disable system restore then re enable it, thus removing all previous restore points and freeing up that lost space!

How to delete inactive System Image Restore Points in System Restore

Windows 10 64-bit.
When I click "show more restore points" in System Restore I see a bunch of old "system image restore points" that were deleted in past and do not correspond to any currently active restore points. Clicking any of these old restore points, I simply get an error message saying they could not be found, and to select another restore point instead.I would like to delete these restore points listings but have been unable to do so.
So far, I have tried steps mentioned below without any luck :

Disk Cleanup through (C Properties
Disable System Protection (OFF and ON) in System Protection for OS (C
Disk Space Usage to minimum (slider button all the way to the left then 'Delete all restore points for this drive'),
Delete all shown Restore points in CCleaner (the problem ones do not show here),
Reset Windows Backup to Default in Windows 10 with 'Reset_Windows_Backup.bat' utility.

Any suggestions highly welcome.
