This is quite a good idea, but you have to compare it in the longer run. If you look at short term results you can get demotivated when you have lack of progress or when you get worse.
If you want I'll post my progress as well (together with my routine then)
The most beneficial to me to keep stretching is to get a set routine and stick to it, keeping in mind that if I do that I can do the splits someday.
So from today on I'll try to monitor my progress with the front (back leg sideways) and sideplit.
