$150,000 / 365 days = $410 per person per day
Your figures for a Reserve unit offer $1,000,000 for 100 pers = $10,000 per person.
Reserve units are funded historically at about 35 days per person (someone can correct me if they have new figures.)
$10,000 / 35 days = $285 per man per day
So, we're spending about 70% per person in the Reserves of what we do on a Reg Force member. The major difference is likely in the benefits that Reserves aren't entitled to as Class "A" soldiers - i.e. full time medical, etc.
Depending on which LFA the unit posting those figures was from, and when that funding was granted changes things considerably.
The national funding model assigns 37.5 days (Sept-May) plus 7 days collective training (summer or other) to each LFA for each soldier in their class A target strength, plus CLDA (old FOA), plus O&M, plus some full-time Reserve positions.
Regional variations make it difficult to compare units in two different LFAs (or sometimes within the same LFA). Different levels of decentralization between LFAs and CBGs leads to differing unit funding levels that may or may not be material - for example, units in 38 CBG have full-time Reservists paid by the CBG HQ, not the unit; in 33 CBG the units hold that funding. So 38 CBG units appear to have smaller budgets than their peers in 33 CBG, but it's an accounting artifact.
The "simple" version of the funding for a unit would be:
Auth class A strength * (37.5 days per person + 7 days per person + CLDA for some trg events + O&M factor) + Auth class BA strength * (365 days per person + CLDA + O&M)
LFDTS holds individual training funds, which would be on top of the funding above.
LFAs and their subordinate ASGs may, of their own volition, download other funds to units to pay for expenses such as utilities or rented transportation - this skews some reporting, as again, there isn't a uniform standard nor reporting framework.
Frankly, DND's chart of accounts and financial reporting are both a mess - but that's much larger than just a Reserve force issue.
