Update account statement & Update Main Wallet

Am I right if I say:

Update account statement every X s : affect , among other things, hist_ variables

Update Main Wallet every Y s: affect , among other things, Exposure

This refering to the "General Option" tab under "Settings". Can anyone confirm or deny ( am I right or wrong? ).

Update account statement every X s : affect , among other things,  hist_ variables

Yes, of course. It is in fact written in the General Options tab, next to Account Statement:

All Win/Lose History variables will be calculated from the account statement records.

Update Main Wallet every Y s: affect , among other things, Exposure

Yes, that's right too.

My trigger waiting for a new value in hist_1, despite that, the Trigger  rather often misses the last_lost (it often takes the previous value). So I have now changed the Account statement update to 5 s and wallet to 15 s (as long there are exposure there will be no triggering), still misses sometimes.

Does the last_lost take extra time to calculate, relativly hist_1_backp for example?

I solved it with a more elegant solution - used hist_1_time parameter instead.
