When you warm up and seal you should have 145# or slightly better. The 100# cold with the +/-5 is good all around for cold as there is enough compression for ignition.

Could be the cranking speed is lower than normal or the engine is tired (worn rings).
Squirt a teaspoon of oil into each cylinder and retest. If the compression increases close to normal, I'd suspect the rings.
