If Robyn has any fault it lies within clarifying the use of a 130/84 temp gradient. It's really not a fault either, he puts endless effort in to make people understand.

When Robyn suggests using a 130 degree basking temp he is strictly talking a surface temperature. It is important to know the difference.

Many people unknowingly give their dragons access to hotspots of 120,130(surface) maybe higher. Fixed digital thermometers or digi's with attached probes will not read a surface temperature accurately. So, if a poster with a digi probe claims to have a 100 degree hotspot, he is reading the air temp at the hotspot. Use a temp gun on the same area and you will be seeing 120,130, and higher.

It's the same principle as you point out BDlvr...the 90 degree day but the ground is much hotter on your feet.
