Charge temp table in real

Hi, i was curious about this feature. First, its not clearly defined in help for me: "0% means IAT value, 100% means CLT value".
I was thinking: 0% value = 100% IAT+CLT fuel correction used , 100% value = 0% iat correction used, only CLT(warmup) correction used.

But today i just test it on hot car, cca 90deg clt(=0% clt correction) and heatsoaked 50deg IAT-open element,manifold mounted. Ambient temp 19degC.
After engine start, i simply rised charge temp value, AFR goes leaner. Exact opoosite i expet for a feature which may bandaid heatsoak.

So now i feel, that description really means, 100% chargetemp value = IAT temp uses CLT temp value and that make non sense isnt?

If so, how may i(we) use it against heatsoak?

May i set it first(somehow) and add fuel in VE map to enrich back to target. Then it will start to work as it supposed to? But still kind of breakneck...

Like it´s written in the help. Charge temp means(in percentage) temp. between IAT and CLT, not the influence of IAT and warmup corrections. ;)
For example:
IAT= 0°C
CLT= 100°C
Charge temp 0% = 0°C
Charge temp50% = 50°C
Charge temp100% = 100°C


Of course, if I understand it right

Seems to work backwards for me too, from what I've tested so far.
