Nylock Mod - Inconsistent Readings with Prusa Level

Hello,
I have been having 1st layer issues near the back corner of the bed so I decided to try to nylock mod. Got everything set up but when I read the bed values I get pretty inconsistent readings. Here are 3 reading back to back with zero changes. Any thoughts whats happening here and what I should do next?

Yes, your 3 runs were at different temperatures. From the timestamps they were done consecutively.  For a start the bed as it heats will expand and change the values.    Second the pinda probe itself is temperature dependent, its readings will also change based on its temperature.  While the 'Super Pinda' is supposed to have better compensation to the older Pinda it will still have these effects.  

This is why its is ALWAYS best to preheat the bed for 5-10 minutes before starting a print or doing anything to check levels.

Well I did on the first one, and then rand the second two in a row. I'd make the slightest change and the values on several of the bolts would vary greatly. I'll try it with 10 min per, but I don't think that's gonna be the thing.

Maybe better luck with the silicone mod.

the readings will never be the same, there will always be run to run variance. what i do is run the test 3X, and only if a reading is consistently high or low, I make a small adjustment. then run it 3X again. my rule of thumb is not to have anything red, otherwise it's fine.

based on your readings, the right side needs a bit more tuning. the left side is fine.
